The graph represents the straight-line motion of a car. How far does the car travel between t = 2 seconds and t = 5 seconds?

An object is thrown vertically into the air. Which of the following five graphs represents the velocity (v) of the object as a function of the time (t)?

A stone is thrown horizontally from the top of a 20-m high hill. It strikes the ground at an angle of 45°. With what speed was it thrown? 14 m/s
20 m/s
28 m/s
32 m/s
40 m/s

A projectile is fired over level ground with an initial velocity that has a vertical component of 20 m/s and a horizontal component of 30 m/s. Using g = 10 m/s the distance from launching to landing points is:

40 m
60 m
80 m
120 m
180 m
