P3 (25 Pts): A small cart that carries a single-turning vane rolls on a level track. The cart mass is M = 5 kg, and its initial speed is U = 5 m/s. At t = 0, the vane is struck by an opposing jet of water, as shown. Neglect any external forces due to air or rolling resistance. Determine the jet speed V required to bring the cart to rest in (a) 1 s and (b) 2 s. In each case, find the total distance traveled. 0 = 60 U = 5 m/s M = 5 kg D = 35 mm U
