1. A motorist uniformly accelerates from 26 m/s to 32 m/s in 4.0 seconds while passing another car.
a) What is the acceleration of the car?
b) What distance does the car travel while passing the other car?
2. A model airplane needs to achieve a velocity of 20 m/s before it can take off. It is capable of accelerating at a rate of 0.80 m/s^2 What is the shortest runway that can be used to operate this plane?
3. A motorcycle starts from rest and accelerates uniformly for 5.0 seconds. During this time, it travels a distance of 140 m. At what rate was it accelerating?
4. An airplane flying at a velocity of 165 m/s accelerates at a rate of 7.0 m/s^2 for 5.0 seconds. What is the final velocity of the plane?
5. A ball starting from rest accelerates at 6 m/s^ down an inclined plane for 2.5
seconds. What is the velocity of the ball at the end of the 2.5 seconds?
