Q. A cart is propelled over an xy plane with acceleration components ax = 4.5 m/s2 and ay = -1.5 m/s2. Its initial velocity has components v0x = 9.8 m/s and v0y = 13.7 m/s. In unit-vector notation, what is the velocity of the cart when it reaches its greatest y coordinate?
Q. The three ropes in the figure are tied to a small, very light ring. Two of the ropes are anchored to walls at right angles, and the third rope pulls as shown. What are and the magnitudes of the tension forces in the first two ropes?
