Let's consider that two hockey players with equal mass, moving with the same speed of 10 km/h collide head-on, as follows: the players collide head-on into each other; instead of colliding into each other, the players collide head-on into the sidewall. In which case the impact force is greater? Assume that the collisions are perfectly inelastic and that the collision time is the same. What changes in regard to the impact forces if we consider that the collision time in the second case is half of the first one?

A truck of mass 9M is moving at a speed v = 15 km/h when it collides head-on with a parked car of mass M. Spring mounted bumpers ensure that the collision is essentially elastic. Find the final velocities of each vehicle. Repeat for the case of the car moving at speed v= 15km/h and colliding with the stationary truck. What fraction of the incident vehicle’s kinetic energy is transferred in each case?

In the figure below, two long barges are moving in the same direction in still water, one with a speed of 10 km/h and the other with a speed of 20 km/h. While they are passing each other, coal is shoveled from the slower to the faster one at a rate of 1100 kg/min. How much additional force must be provided by the driving engines of each barge if neither is to change speed? Assume that the shoveling is always...
