Answer Key
1.Given the displacement vs time graph below, answer the following: (a) where is the object at t = 5 s? (b) What is the velocity of the object between t = 4 s and t = 5 s? (c) How about between t = 9 s and t = 11s? (d) What happened on the object between 8-9 seconds? (e) What can you say on the objects acceleration as it approaches the 10- second mark?
2.A car starts from rest and uniformly speeds up. It reaches a speed of 5.0 m/s in 10 seconds. What is the acceleration? How far is it from the origin after the given time interval?
3.A skydiver slows from 52 m/s to 8m/s within 10 seconds as his parachute opens. Calculate the magnitude of his acceleration (assumed constant) and the distance he falls while the parachute is opening? (Ans. -4.4 m/s2, 300 m)
4.A pebble is thrown vertically down from a bridge with initial velocity 10 m/s and strikes the water in 2 seconds. Find (a) the velocity with which the pebble strikes the water below and (b) the height of the bridge. (Ans. 29.6 m/s, 39.6 m)
5.Do you recall Galileo’s famous experiment at the leaning tower of Pisa? The tower is 55-m high. If Galileo had accidentally dropped one of the rocks 0.5 s before the other, with what velocity would the second rock have had to be thrown downward to reach the ground at the same time as the first rock?
