What is speed per hour if you travel 288900 kilometers in 2 minutes 29 seconds?

To calculate speed, you first convert the time to hours: 2 minutes 29 seconds is 2.4833 minutes, or approximately 0.0414 hours. Next, divide the distance traveled (288900 km) by the time taken (0.0414 hours) to find the speed. The speed would be approximately 6,970,531 km/h.

Two boats leave from the same dock traveling in opposite directions The first boat is traveling 25 mph and the second is traveling 29 mph How long will it take before they are 162 miles apart?

To calculate the time it takes for the two boats to be 162 miles apart, you can use the formula: time = distance / relative speed. The relative speed of the two boats is the sum of their speeds, which is 25 mph + 29 mph = 54 mph. Then, time = 162 miles / 54 mph = 3 hours. So, it will take 3 hours for the two boats to be 162 miles apart.

What are the forces in net force?

Any time an object's velocity changes (the object "accelerates"), that is due to a net force. Here are some examples:

* A car speeds up. The force is exerted by the tires, on the road.

* A car slows down. The force is exerted by the tires, on the road, or by air resistance.

* A car moves in a curve (its velocity changes too, since it changes direction). The force is exerted by the tires, on the road.

* A planet moves around the Sun. The velocity changes all the time, since the direction changes. The force is exerted by gravity.

* A falling object speeds up. The force is exerted by gravity.

What is the national average of primary care visits per hour per physican?

The national average of primary care visits per hour per physician is typically around 20-25 visits. This can vary based on various factors such as practice setting, physician workload, patient population, and practice efficiency. It is important for physicians to balance seeing enough patients with providing high-quality care.

What is the kinetic energy of a softball traveling at a speed of 30 moles per seconds if the baseball has a mass of 0.13 kg?

30 miles per second? Covert to meters per second

30 miles/sec =(1609 meters/1 mile)

= 48270 m/s ( very fast!)

KE = 1/2mV^2

KE = 1/2(0.13 kg)(48270 m/s)^2

1.51 X 10^8 Joules

How many seconds to cover a mile at 550 mph?

It would take approximately 3.6 seconds to cover a mile at a speed of 550 mph. This can be calculated by dividing the distance (1 mile) by the speed (550 mph) and converting the result to seconds.

What is the top speed of a mini dirt bike 49cc?

25-27-mph standard top speed for a mini dirt bike

Can you go pi mph?

So say you have a circle that is one mile in diameter. If you can travel the circumference of that circle in exactly one hour, then you can indeed travel at a rate of pi mph.

Is kinetic energy or potional energy bad or good?

it is gooad and bad. The things is it really depends

Which type of energy is the waste energy?

Waste energy is quite often in the form of heat energy.

Can kinetic energy become potential energy?

Energy is never created or destroyed, but different forms of energy can be converted into another. For example, potential energy is the energy of position; a pendulum at the peak of its swing, or a spring tightly compressed. It can be converted into kinetic energy, for example, the pendulum swinging rapidly at the bottom of the swing, or the object propelled by the spring.

How many kmh in 220 mph?

There are approximately 1.609 kilometres per mile, so divide 220 by 1.609, or approximately 136.73 mph.

What is 17 kph in mph?

1 mile = 1.6 km,

17 km / 1.6 = 10.625miles

10.625 mph roughly 11 mph

Google says 10.5633103 mph

How fast is 320 km in MPH?

320 km is approximately equal to 199 miles per hour (mph).

How fast is 630 fpm in mph?

630 feet per minute (fpm) is equivalent to about 7.16 miles per hour (mph).

How fast is 79 mach in mph?

This is the rough formula.

Mach = velocity/speed of sound

This is rough because conditions are truly variable, but............

79 Mach = velocity/768 mph

= ~606070 miles per hour

How fast is 55 mph on a ATV in mph?

If an ATV is moving at 55 mph, then its speed is 55 mph. Both the original speed and the converted speed are the same.

How many mph can a f-22 raptor go?

The F-22 can go faster than 1.500 mph (2.400 km/h). Exactly how much faster is still a well guarded secret.

It can be as little as 100 mph faster or as much as 600 mph faster. The F-22's deadliness doesn't come from its maximum speed, it comes from its stealth capabilities, excellent sensor-fusion techniques and a very finely tuned radar system.

What is 35 kph in mph?

35 kph is 21.75 mph.
35 kph = 21.75 mph

What is the kinetic energy in joules of a 850 lb motorcycle moving at 66mph?

Answer= 5703.55 Joules (see below for explanation)

So Kinetic energy= 0.5 mv2

Unit-wise 1 Joules = 1 kg m2s-2

Therefore we need to convert 66mph -

1 mph= 1.61 km/h

66mph=106.22 km/h= 29.51 m/s =v OR (106.22 x 1000)/(60x60)

Also need convert 850lbs to kg-

1kg= 2.2 lbs

1/2.2 kg = 1 lb

Therefore 850 lbs= 1/2.2 x 850= 386.55 kg= m

Back to the original equation KE= 1/2 mv2

= 0.5 x 386.55 x 29.51

= 5703.55 Joules = 5.7 KiloJoules

When electrons bombard the target what percent of their kinetic energy is converted to heat?

Approximately 99% of the kinetic energy of electrons is converted to heat when they bombard the target. This conversion occurs due to interactions with the target material, resulting in the release of thermal energy.

What are some objects that have kinetic energy?

Kinetic energy is the energy an object has due to its mass and its velocity. Kinetic energy is calculated with the equation: Ek = ½ mv² Since kinetic energy is proportional to mass and velocity, any object moving very slowly has a small amount of kinetic energy. Also, any very small object normally has a small amount of kinetic energy. For example, a soccer ball rolling down a hill might have a relatively small amount of kinetic energy.
