4. You need to show your work in detail to get any credit.
Before collision:
The red car (on the left) has the velocity of
10.0 m/s and mass of 4.8 kg.
The blue car (on the right) has the velocity
of -5.6 m/s and mass of 4.4 kg.
After elastic collision:
The blue car moves with the velocity of 8.8 m/s.
(a) What is the initial momentum of the red car?
(b) What is the initial momentum of the blue car?
(c) What is the total momentum of the system of blue and red car before collision?
(d) What is the final momentum of the blue car?
(e) What is the impulse on the blue car (in kg.m/s)?
(f) Is the system consisting of the blue and red car an isolated system?
(g) What is the impulse on the red car (in kg.m/s)?
(h) What is the velocity of the red car after the collision?
(i) Draw annotated p-t and F-t graphs for both carts at all stages of collision. Assume that
collision occurred for 0.5 seconds.
