Kinematics

To convert speed to meters per second, we divide by 3.6 (1 km/h = 1000 meters / 3600 seconds). Thus, a car traveling at 50 km/h is 13.89 m/s. To find the time taken to cover 60 meters, we use the formula time = distance / speed, which is 60 meters / 13.89 m/s = 4.32 seconds.

At 60 mph it would take 3.41 seconds to cross an American football field.

A really long time; about six months at 55 miles per hour.

No, not all of the potential energy has been changed to kinetic energy. Some of the potential energy will be dissipated as heat due to air resistance and friction between the skis and the snow upon landing.

A plane climbs into the jet stream which is flowing at a rate of 80 miles per hour Traveling with the jet stream for 5 hours the plane covers 1150 miles The plane then reduces its altitude and flies 150.

Kinetic energy and potential energy are not usually proportional. In the general situation, you can't derive potential energy from kinetic energy. In specific cases, sometimes you can - especially if you assume that potential energy that existed previously got converted to kinetic energy, or vice versa.

The formula for kinetic energy is: KE = mv^2, in which m is mass in kilograms and v is speed in meters/second, or m/s. The unit for kinetic energy is the Joule (J), which is one kilogram·m^2/s^2. If the speed of a mass is halved, it's kinetic energy will be reduced by one quarter. For example, if a 1 kg mass has a speed of 4 m/s, its kinetic energy = 1 kg(4 m/s)^2 = 16 J. If the speed of the 1 kg mass is halved to 2 m/s, its new kinetic energy = 1 kg(2 m/s)^2 = 4 J.

The acceleration due to gravity on Earth is approximately 9.81 m/s^2, while on the moon it is only 1.62 m/s^2. This means that a baseball will accelerate more slowly on the moon compared to Earth due to the lower gravitational force.

Motion. The motion can be energized by virtually any source of energy.

Potential energy is used to get the roller coaster car up the first hill. The potential energy is converted to kinetic energy as the car goes down the hill. The potential energy is typically provided by a motor or chain lift system.

Potential energy is gained as the roller coaster car goes up to the top of the first hill. This type of energy is due to the car's height above the ground and its potential to do work as it moves downhill.

No, the inertia of a bowling ball is greater than the inertia of a basketball due to the bowling ball's larger mass. Inertia is the resistance of an object to changes in its state of motion, and a heavier object like the bowling ball requires more force to accelerate or decelerate compared to the basketball.

Any object which is moving from a lower level to a higher level is converting kenetic energy (ie climbing a set of stairs for example) to potential energy. A car which has been parked at the top of a hill has used kenetic enegry to get up there and has potential to roll down to the bottom of the hill if the brake is released.

The man would have to go at a speed of 222 miles per hour to cover 555 miles in 2 hours and 30 minutes.

The plane was in the air for 4.5 hours (1,350 miles divided by 300 miles per hour).

The plane was in the air for 4.5 hours. This can be calculated by dividing the distance (1350 miles) by the average speed (300 miles per hour).

Force can be defined as the derivative of momentum with respect to time or: dp/dt = d(mv)/dt

Since the mass stays the same, we can take that out:

m * dv/dt (It's worth noting that this is the derivation of the F=ma equation)

Now to answer your question, this depends on the amount of time the object is being pushed by the wall. If the time is equal, then the wall will apply a greater force on the ball if it bounces back because it has to change the ball's momentum by a greater amount to get it to move back towards the thrower.

At the point where the ball is released, potential energy is at its highest (transferred from the person's hand) and kinetic energy begins to increase due to the ball's motion. This transition typically occurs between the letters 'A' and 'B'.

Temperature is a measure of the average kinetic energy of the particles in a substance. The higher the temperature, the more kinetic energy the particles have. Temperature is commonly measured in units such as degrees Celsius (°C) or Fahrenheit (°F).

Sustained winds of 50 knots are in the middle of the range of a tropical storm.

A knot is a nautical mile per hour, so since a nautical mile is about 1.15 miles, a knot is about 1.15 miles per hour. Therefore, 50 knots is about 58 miles per hour or about 93 km/h.

According to Newton's second law, F=ma. That is, the bear's acceleration should be proportional to the total force acting on the bear. As the bear's velocity is constant, its acceleration is zero. Therefore, the total Force acting on the bear is zero. Thus, the friction has to be equal in magnitude and opposite in direction to the bear's weight. As W=mg, we get that its weight is 9.8*400=3,920 Newton. Thus, the friction acting on the bear is 3,920 Newton upwards.

i have a 1990 Indy 650 with tripple pipes, plastic skis and racing clutch weights and i have got it to go 110 mph but i am shure it will go at least 120 mph

1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second

1 hour = 60 minutes = 3600 seconds

1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
