A 75.0 kg ice skater moving at 8.50 m/s crashes into a stationary skater of equal mass. After the collision, the two skaters move as a unit at 4.25 m/s. If the impact time is 0.140 s, what are the magnitudes of the average forces experienced by each skater during the collision? Force experienced by moving skater Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.

Vo V M A four-wheel cart of mass M = 95 kg is moving along a horizontal surface with a constant velocity V = 3.5 m/s relative to the ground. A person of mass m1 = 65 kg carrying a backpack of m2 = 8 kg runs and catches up to the cart, and then jumps onto the cart. Just before landing on the cart, the person is moving parallel to the ground and the velocity of the center of mass of the system including the person, backpack and cart is VCM = 5 m/s. 19) What is the horizontal momentum of the person after landing on the cart? Pf = 228 kg m/s Pf = 455 kg m/s Pf = 325 kg m/s 20) Compare the total kinetic energy of the system (including the person, backpack, and cart) before the person has landed on the cart to after. KEbefore > KEafter KEbefore = KEafter KEbefore < KEafter 21) The person now holds the backpack off the back of the cart and lets it go. The backpack falls to the ground. What happens to the speed of the cart when the backpack is dropped? increases decreases remains the same
6.3 PQ1 Newton's second law can be stated that the force is equal to the rate of change of momentum, F = d(mv)/dt. Tak- ing the derivative by parts yields F = m(dv) / (dt) + v(dm) / (dt). This does not correspond to F = ma. What is the source of the discrepancy? %3D
