Question
Problem 8 8 Before VBI Initially at rest Cart A Cart B Iwo carts are riding on an air track as shown in the figure. At time t-0 s, cart B is at the origin and traveling in the negative x direction with velocity VBl. At that time, cart A is at the position shown and is at rest. Cart B has twice the mass of cart A. The carts "bump" into each other but do not stick. Which physical parameter can be described by each of the following graphs? Watch out for signs! (For each statement select Force, Position, Velocity. Acceleration, Momentum, or None of these.) 0 -1 0 100 TimeExplanation / Answer
1) for graph 1)
At t= 0 , b has positive velocity, which is not possible.
NONE OF THESE. ans
2) for graph 2 it may be FORCE OR ACCELERATION.
Please try both as I don't know which options are there.
3) again at t= 0 , a has something positive in magnitude, which is not possible for any of the given physical quantities.
NONE OF THESE. ans
Please let me know, if it was helpful. Thank you so much.
