Momentum Problem on Motion sensor

[susie__]

Homework Statement

2001 M1
A motion sensor and a force sensor record the motion of a cart along a track, as shown above. The cart is given a push so that it moves toward the force sensor and then collides with it. The two sensors record the values shown in the following graphs.
a. Determine the cart's average acceleration between t = 0.33 s and t = 0.37 s.
b. Determine the magnitude of the change in the cart's momentum during the collision.
c. Determine the mass of the cart.
d. Determine the energy lost in the collision between the force sensor and the cart

Homework Equations

The Attempt at a Solution

a) Average Acceleration = delta v /delta t
=.092 m/s^2

b) I'm stuck here

I don't think we'll be able to help without seeing the graphs! Could you post them?

because I don't have the values for the force sensor graph. Without that information, I cannot determine the change in momentum.

c) Mass = m = F/a
= 5 N / .092 m/s^2
= 54.35 kg

d) Again, without the values for the force sensor graph, I cannot determine the energy lost in the collision. The force sensor graph would provide information on the force applied during the collision, which is necessary to calculate the energy lost.
