Two blocks collide on a frictionless surface. After the collision, the blocks sticktogether. Block A has a mass M and is initial
ly moving to the right at speed v. Block B has amass 2M and is initially at rest. System C is composed of both blocks. (a) Draw a free-bodydiagram for each block at an instant during the collision. (b) Rank the magnitudes of thehorizontal forces in your diagram. Explain your reasoning. (c) Calculate the change inmomentum of block A, block B, and system C.Anybody want to take a crack at this?

Answer:
The net force on the skater is zero. ()
Explanation:
According to Newton's First Law, an object is at equilibrium when either it is at rest or moves at constant velocity, which means a net force of zero. Based on the given statement, there are no external forces acting on skate and, therefore, the net force on the skater is zero. ()
