Question

a). Rank the momentum of the following six objects from least to most. The arrows are proportional to the velocity of the objects and no arrow indicates a velocity of 0 m/s. Assume that right is the positive direction. If two momenta are the same, give them the same rank. 10 kg 20 kg 10 kg C. 20 kg 10 kg b). For the following impulse acting on an object, sketch a possible change in velocity for the object Force time c). Sketch a possible impulse for the following graph of an object's velocity vs. time. time

Explanation / Answer

7) a)   Momentum = p = m*v

Rank of momentum is

B = C < E < A < D

b) Change in velocity = Area under the curve (F-t)/Mass of object

So, the sketch will be almost same with smaller area as that of mass time.
