Question

A small, 250\g cart is moving at 1.50m/s on a frictionless track when it collides with a larger, 4.00kg cart at rest. After the collision, the small cart recoils at 0.890m/s .

What is the speed of the large cart after the collision?

Answer 1

ill be happy to check your answer

Answer 2

honesty was just hoping for a formula if possible, don't need the answer but unable to figure out how to set up the problem

Answer 3

Another conservation of momentum problem

m1*u1+m2*u2 = m1*v1+m2*v2

m1 = 250 = .25kg
u1 = 1.5
m2 = 4
v1=.89

solve v2
