Calculate the percentage loss of energy and velocity, Mechanical Engineering

1. The three freight cars are rolling along the horizontal track with the velocities shown in the Figure. After the impacts occur the three cars become coupled together and move with a common velocity  v. The loaded cars A, B and C have masses of 60kg, 50kg, and 75kg, respectively. 

a. Determine the velocity v ,

b.   Calculate the percentage loss of energy of the system due to coupling.
