1. You are at a football game. The football is kicked with an in1.  A train started from rest and moved with constant acceleration. At one time it was traveling 30 m/s, and 160 m farther on it was traveling 50 m/s. Calculate (a) the acceleration, (b) the time required to travel the 160 m mentioned, (c) the time required to attain the speed of 30 m/s, and (d) the distance moved from rest to the time the train had a speed of 30 m/s. (e) Graph x versus t and v versus t for the train, from rest.

2.  Two subway stops are separated by 1100 m. If a subway train accelerates at +1.2 m/s2 from rest through the first half of the distance and decelerates at -1.2 m/s2 through the second half, what are (a) its travel time and (b) its maximum speed? (c) Graph x, v, and a versus t for the trip. itial velocity of 20.0 m/s at an angle of 35° above the ground. What is the maximum height that the ball achieves ?
