A 2 kg object initially moving with a constant velocity is subjected
to a force of magnitude F in the direction of motion. A graph of F
as a function of time t is shown. What is the increase, if any, in the
velocity of the object during the time the force is applied?
(A) 0 m/s (B) 2.0 m/s (C) 3.0 m/s (D) 4.0 m/s (E) 6.0 m/s
72. A disk slides to the right on a horizontal, frictionless air table and collides with another disk that was initially
stationary. The figures below show a top view of the initial path I of the sliding disk and a hypothetical path H
for each disk after the collision. Which figure shows an impossible situation?
