Practice Problems Set 1: Kinematics
1. You are throwing a ball straight up in the air. At the highest point, the ball’s
a) velocity and acceleration are zero
b) velocity is nonzero but its acceleration is zero
c) acceleration is nonzero, but its velocity is zero
d) velocity and acceleration are both nonzero.
2. An object goes from one point in space to another. After it arrives at its destination, the
distance it travelled is:
a) either greater than or equal to
b) always greater than
c) always equal to
d) either smaller than or equal to
e) always smaller than
f) either smaller or larger than
the magnitude of the displacement.
3. The graph shows position as a function of time for two trains running on parallel tracks.
For times greater than t =0, which is true:
a) At time tB, both trains have the same velocity.
b) Both trains speed up all the time.
c) Both trains have the same velocity at some time earlier than tB,.
d) Somewhere on the graph, both trains have the same acceleration.
4. A person standing at the edge of a cliff throws one ball straight up and another ball
straight down, each at the same initial speed. Neglecting air resistance, which ball hits
the ground below the cliff with the greater speed?
a) ball initially thrown upward;
b) ball initially thrown downward;
c) neither; they both hit at the same speed.
