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 %3D 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. KEpefore > KEafter KEpefore = 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

Two fun-loving otters are sliding toward each other on a muddy (and hence frictionless) horizontal surface. One of them, of mass 7.50 kg, is sliding to the left at 5.00 m/s while the other, of mass 5.75 kg, is slipping to the right at 6.00 m/s. They hold fast to each other after they collide. (a) Find the magnitude and direction of the velocity of these free-spirited otters right after they collide. (b) How much mechanical energy dissipates during this play?
Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass m, = 70.0 kg moves in the negative y-direction at 2.00 m/s and skater B with mass m. = 90.0 kg moves in the negative x-direction at 4.00 m/s.

One day while out on a space walk to repair your ship, you notice that you have forgotten to tie off your tether! You and the heavy wrench you are carrying are drifting slowly away from the ship with a velocity of V1 = -1.92 m/s (this is negative since you are moving left in the figure). Your mass (including your suit) is M = 139 kg and you are carrying a wrench of mass m = 9.46 kg. You are one smart astronaut and and you throw the wrench in the direction away from your ship as hard as you can. The result is that afterward, your velocity is V2 = 0.65 m/s (this is positive since you are now moving right in the figure).Determine all the following:The velocity of the wrench at moment 2: v2 = m/sThe total kinetic energy of you and the wrench before the throw: KE1 = JoulesThe total kinetic energy of you and the wrench after the throw: KE2 = JoulesWhere did all the extra energy come from at moment #2?
