How fast is 160 kph in miles?

16 kph = about 10 mph (9.94193908 mph)

Is 696 meters per minute the same as 2088 feet per minute?

No, 696 meters per minute is not the same as 2088 feet per minute. To convert meters to feet, use the conversion factor 1 meter = 3.281 feet. So, 696 meters per minute is equivalent to approximately 2283 feet per minute.

How many mph is a 5.7 on the 40 yard dash?

A 5.7 second 40 yard dash is roughly equivalent to maintaining a pace of about 11 mph.

In physics what is variable acceleration and please give at least two examples of it?

Variable acceleration refers to an object's velocity changing by different amounts over time. This means that the object's speed is not changing at a constant rate. An example of variable acceleration is a car speeding up as it merges onto a highway, where the acceleration is increasing. Another example is a rocket slowing down as it enters the atmosphere due to air resistance, where the acceleration is decreasing.

When velocity is changing what is happening to the slope on a position versus time graph?

That slope is the 'speed' of the motion. If the slope is changing, then the speed

is changing. That's 'accelerated' motion.

(It doesn't matter whether the speed is growing or shrinking. It's still 'accelerated'

motion. 'Acceleration' does NOT mean 'speeding up'.)

How many drops per second are necessary to create a stream?

It depends on the flow rate of the stream. Typically, thousands of drops per second are needed to form a continuous stream visibly.

How fast is 250kph in mph?

155.34 mi

Algebraic Steps / Dimensional Analysis Formula 250 km*100000 cm

1 km*1 in

2.54 cm*1 mi

63360 in=155.3427981 mi

Direct Conversion Formula 250 km*1 mi

1.609344 km=155.3427981 mi

What does 40 kmph mean?

40 'kilometers per hour'. It is equal to 24.86 miles per hour.

Is it true that you find acceleration when initial velocity final velocity and time are given?

With that information, you can find the average magnitudeof the acceleration

during that period of time. You can't tell what either the magnitude or direction

were at any time during, only the average magnitude for the whole interval.

Is the inertia of a body equal to its mass?

Inertia is related to the mass, and it is proportional to the mass. When measuring things, you will usually measure the mass, not the inertia - but it basically amounts to the same. Just consider the mass to be what gives an object its inertia.

What happens to kinetic energy and potential energy of a car when it accelerates up a hill?

What happens to kinetic energy when your car stops at the end of the track?

It's all about energy?

The first question to ask yourself is," What stops your car?

Most people would say, "The brakes stop the car."

What happens to the brake as the car is stopped?

Due to friction, they heat up and the brake pads wear out?

What does it mean for brake pads to wear out?

The brake pads get thinner as they rub on the spinning rotor.

What causes them to get thinner?

The friction breaks the chemical bonds in the material of which they are made.

The Kinetic energy is converted into heat and used to break the bonds between the molecules in the material of which the brake pads are made.

If you push hard enough on the brake pedal, the tires will stop turning, and the car will skid to a stop. In this case, the tires will give off heat due to friction and the tires will wear thin as the chemical bonds between the molecules in the material of which they are made are broken.

Good site for explanation of brakes!

What are kinematics when applied to secondary machining techniques?

Casting, forming, forging, extruding and molding are primary machining. Material removal and change of shape, drilling, grooving, dimensional corrections are some very special specific techniques, which are used in specialist workshops or machines are suppose to be the secondary machining, Turning, milling, drilling grinding, shaping are some of the secondary machining process. Chuck, face plate, vice, jigs, fixtures special centers are the work holding devices. Vernier calipers, micrometer, compactors, depth micrometers are some of the measuring tools using for secondary machining Turning, threading grooving, parting tools, milling cutters, taps drill bits, etc are cutting tools using for secondary machining techniques. Cutting speed, Speed, Feed rate, etc are the cutting parameters Inspections, verification, comparison, are the quality control methods in this kinematics. Assessments of health and safety measures are yet another kinematics in this technique.

What is 29 kph in mph?

29 kilometers per hour is equal to approximately 18 miles per hour.

How fast was Jackie Robinson in mph?

Jackie Robinson was known for his speed on the baseball field and was estimated to be able to run the 100-yard dash in 10 seconds. This would equate to a speed of approximately 18 miles per hour (mph).

When winds inside a tropical cyclone reach 74 mph what occurs?

When winds inside a tropical cyclone reach 74 mph, it is classified as a hurricane (Category 1) in the Atlantic basin and a typhoon in the Pacific. At this wind speed, a tropical cyclone becomes more organized and can cause damage to infrastructure and pose a threat to life and property.

Whereas impulse involves the time that a force acts work involves what factor?

Work involves both the magnitude of force and the distance over which the force is applied. Work is calculated by multiplying the force exerted on an object by the distance the object moves in the direction of the force.

How many mph is 100 yards 11 seconds?

To find out how many mph is 100 yards in 11 seconds: First, convert 100 yards to miles (100 yards = 0.057 miles). Next, calculate the speed by dividing the distance (in miles) by the time (in hours) - 0.057 miles / (11 seconds / 3600 seconds) = 19.64 mph.

How much time for 260 miles at 80 mph?

about 5 hours and 45 minutes You can find the answer by dividing 430 by 80 to get 5.375 hours. To convert tenths of an hour to minutes, multiply .375 by 60 and you get 22.5 minutes. So the answer is 5 hours and 22.5 minute (if you don't stop).

How fast is 1.7 mph in kmh?

1 mile = 1.609344 km

→ 17 mph = 17 × 1.609344 km/h ≈ 27.4 km/h

When an object falls from a height and bounces it's energy changes form When a ball bounces it's potential and kinetic energies change Eventually the ball will stop bouncing Why does the ball stop?

The ball stops bouncing due to a loss of energy through various forms such as heat, sound, and deformation of the ball. As the ball bounces repeatedly, these energy losses accumulate, causing the ball to eventually come to a stop.

How fast is 320 mph in kph?

A kilometer (km) is 5/8 (or 60%) of a mile. So 330 kph x .6 = 198 mph. Or times 330 x .621=204 mph
Quick & easy (& approximate) calculation learned while driving in Germany... multiply by 6 and drop the last digit... 6 x 330 = 1980 = 198mph

How much is 80 miles per hour in kilometers?

There can be no equivalence. Miles per hour is a measure of speed while a kilometre is a measure of distance. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
