Im confuse in this problem, please help me because im having a hard time in solving this problem. The problem goes like this:(adsbygoogle = window.adsbygoogle || []).push({});

A cart of A of mass 2.0[kg] which is moving at a speed of 7.0]m/s] on a horizontal floor collides with the object B of mass 5.0[kg] which is standing still on the floor. After that, A and B are united and start sliding. There is no friction between cart and floor and coefficient of sliding friction between cart and floor and the coefficient of sliding friction between B and floor is 0.20. Set the acceleration by gravity to 9.8[m/s²].

1. Find the speed of the object immidiately after collision.

I have solved the speed of object after the collision and i get 2.0 m/s

2. By solving the equation of motion find the acceleration and force acting between A and B.

i cant solve the 2nd part, how can i get the acceleration?
