Question

A2 kg cart moving initially at 4 m/s strikes a 3 kg cart, initially

at rest. The two collide inelastically, sticking together. What is
their velocity immediately after the collision?

Answer 1

1.6 m/s

Step-by-step explanation:

m1v1 = (m1 + m2)v2

=> 2 x 4 = 5 x v2

=> v2 = 8/5

=> v2 = 1.6 m/s
