Question
In a common physics demonstration, two identical carts having rigid metal surfaces and equal speeds collide with each other. Each cart has a piece of Velcro® at one end and a spring at the other end. See (Figure 1) .
Part A
For collision (a) shown in the figure, find the magnitude of the velocity of the left cart after the collision.
Express your answer in terms of the initial velocity v0.
Part B
For collision (a) shown in the figure, find the direction of the velocity of the left cart after the collision.
Part C
For collision (a) shown in the figure, find the magnitude of the velocity of the right cart after the collision.
Express your answer in terms of the initial velocity v0.
Part D
For collision (a) shown in the figure, find the direction of the velocity of the right cart after the collision.
Part E
For collision (b) shown in the figure, find the magnitude of the velocity of the left cart after the collision.
Express your answer in terms of the initial velocity v0.
Part F
For collision (b) shown in the figure, find the direction of the velocity of the left cart after the collision.
Part G
For collision (b) shown in the figure, find the magnitude of the velocity of the right cart after the collision.
Express your answer in terms of the initial velocity v0.
Part H
For collision (b) shown in the figure, find the direction of the velocity of the right cart after the collision.
Part I
Are both collisions elastic?
Explanation / Answer
In the figure a the collsion is elastic. and the the two carts have same mass so, velocities are interchanged.
A) vo
B) towards left (-x axis)
C) Vo
D) towards right ( +x axis)
In figure figure b when they collide they stick and they do not move either side.
E) zero
F) No direction.
G) zero
H) No direction.
I)
the collision which takes place in figure a is elastic and the collsion which takes place in figure b is completely inelastic.
