(a) How much momentum is transferred in the collisions in Figure 4.23?

(b) Is this momentum transferred from cart 1 to cart 2 , or in the opposite direction?

Figure 4.23 (a) Velocity-versus-time graph and (b) momentum-versus-time graph of two carts before and after the two collide on a low-friction track. The sum of the momenta is the same before and after the collision. The inertias are m = 0.36 kg and m = 0.12 kg. (a) Vx (m/s) 0.6 0.4 cart 2 0.2 22 0 cart 1 -0.2 collision 20 40 60 Av, (b) P.
