1.The speed of a train increased from 15 mi/hr to 25 mi/hr in a distance of 500 ft. Calculate the average acceleration in ft/s2.

2.An airplane taking off from a landing field has a run of 500 m. It starts from rest, moves with constant
acceleration, and makes the run in 30 s. With what velocity did it take off?

3.A bus starts from rest at a station and accelerates at a rate of 2 m/s for 25 s. It then runs at constant speed for 25 s and slows down decelerating at -3m/s2 until it stops at the next station. Find the total distance traveled by the bus.

4.A bus driver forgets to stop at a bus stop. Just as he passes the stop, he begins to decelerate. Five seconds later the bus is 80 m beyond the stop and has slowed to 10 m/s.
a) Calculate the speed of the bus as it passed the bus stop
b) What was the deceleration of the bus? (assumed to be constant)

5.At the instant the traffic lights turn green, an automobile that has been waiting at an intersection starts ahead with a constant acceleration of 2 m/s2. At the same instant, a truck traveling with constant velocity of 10 m/s overtakes and passes the automobile.
a)How far beyond its starting point will the automobile overtake the truck?
b)How fast will it be traveling?
