In a physics lab, a 0.500-kg cart (Cart A) moving with a speed of 130 m/s encounters a magnetic collision with a 1.50-kg cart (Cart B) which is initially at rest. The 0.500-kg cart rebounds with a speed of 50 m/s in the opposite direction. Determine the post-collision speed of the 1.50-kg cart.
Homework Answers
using conservation of momentum
m1v1i + m2v2i = m1v1f + m2v2f
0.5*130 + 0 = 0.5(-50) + 1.5*v2f
65 = - 25 + 1.5*v2f
v2f = 60 m/s

Cart A has a mass of 1.00 kg and is moving rightward at 27.6 m/s prior to the collision with Cart B. Cart B has a mass of 0.50 kg and is moving leftward with a speed of 42.9 m/s. After the magnetic repulsion of the two carts, Cart A is moving leftward at 10.1 m/s. Determine the post-collision speed and direction of cart B.
