A particle of mass m moving along the x-axis with a velocity component +u collides head-on and sticks to a particle of mass m/3 moving along the x-axis with the velocity component −u. What is the mass M of the resulting particle?
Two skateboarders, with masses m1 = 75.0 kg and m2 = 65.0 kg, simultaneously leave the opposite sides of a frictionless half-pipe at height h = 4.00 m as shown in Figure P11.49. Assume the skateboarders undergo a completely elastic head-on collision on the horizontal segment of the half-pipe.

If a cart of mass 350 grams moving at speed of 4.5 m/s hits an end-stop and rebounds at a speed of 3.2 m/s, what is the change in momentum, in units of kg.m/s? A cart has the rubber bumper attached to the force sensor, and it moves and collides with an end-stop. In the collision, it suffers a change in momentum = 4.05 kg.m/s, and the time during which the collision takes place is 0.182 seconds. Calculate the average force applied on the cart by the bumper, in newtons.
