On a snowy road, a driver applies a braking force of 6017 N on his 1174 kg car. The car travels between two points a distance of 39.6 m along the snowy road in 2.39 s. How fast is the car moving when it passed by the first point?

A block is sliding with an initial velocity of 4.0 m/s. If the block suddenly begins to accelerate in the opposite direction with a magnitude of 0.5 m/s2, how far does the block slide before coming to a complete stop?

A small block is released from rest at the top of a frictionless incline. The block travels a distance 0.252 m in the first second after it is released. How far does it travel in the next second?

A train accelerates from 100 m/s west to 170 m/s      west in 10 seconds.

Fast Car: On a hot day in the flats, the temperature is 106.2 degrees. A driver finds an empty, flat stretch of desert that is 1913 meters long and decides to push the limits of his car. He finds the car can accelerate from 0 to 60 mph (26.8 m / s) in 4.95 s. Now he wants to see how fast the car can go. Assume the car maintains the same average acceleration until it reaches its top speed of 87.9 m / s. (a) How long will it take the car to reach its top speed? (b) How far will the car travel before it reaches its top speed?

7: A 7500 kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 m/s2 and feels no appreciable air resistance. When it has reached a height of 525 m, its engines suddenly fail so that the only force acting on it is now gravity. a) What is the maximum height the rocket will reach above the launch pad? b) How much time after engine failure will elapse before the rocket crashes on to the launch pad? c) What is the total time the rocket spends in the air? d) How fast will the rocket be moving when it crashes?

A bicyclist is practicing to increase his endurance for a one-hour trip. He has an average speed of 30 m/s in the first 30 min. If the cyclist wants an average speed of 40 m/s for the entire trip, by how much does he need to increase his average speed in the last 30 minutes?
