There are three very similar versions of this question. Each version provides a before-after diagram showing the initial and final momentum of an object. Five sets of collision parameters are presented. One of them would cause the specified change of state. This is one of the three versions:
Version 1
Pre- and post-collision information is shown. Identify the collision parameters that are consistent with the indicated change in momentum. (A + sign indicates a rightward direction; a - sign indicates a leftward direction.)
a. ∆p = +40 kg•m/s
b. ∆p = +8 kg•m/s
c. Impulse = +16 N•s
d. F = +12 N, ∆t = 4 s
e. F = +60 N, ∆t= 3.0 s
