A person with a body mass of 70 kg is standing at rest on frictionless ice. They are also holding a 5 kg watermelon. Suddenly they heave the watermelon away from themselves at an angle of 35 degrees above the horizontal, and with a speed of 5 m/s. How fast are they moving along the ice after they have thrown the melon?

Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.

Someone standing on a hillside throws a ball up a hill with an initial speed of 11.0 m/s. The hill has a slope of θ = 17∘ with respect to the horizontal, and they throw the ball at an angle of ϕ = 23∘ above the slope of the hill. How far away from the person will the ball land, L, in m?

Anza has a mass of 59.1 kg. Ben has a mass of 53.9 kg. The cart has a mass of 26.7 kg. Anza, Ben, and the cart all started from rest (in the laboratory frame of reference). While Anza remained standing on the cart, Ben jumped to the right (just as was the case in the previous question). Ben jumped to the right with a speed of 3.5 m/s relative to the moving cart (so Anza would have seen Ben moving away from her with a speed of 3.5 m/s). Then (after Ben jumped to the right) Anza jumped to the left. Anza jumped with a horizontal speed of 3.3 m/s relative to the moving cart. In other words, after both Ben and Anza jumped, Anza would have seen the cart moving away from her with a speed of 3.3 meters per second. After Anza jumped, what was the velocity of the cart (in meters per second) in the laboratory reference frame? Consider the positive direction to point to the right. The sign of your answer (positive or negative) is important.
