Starting from rest, the cart below is propelled by a hydraulic catapult (liquid jet). The jet strikes the curved surface and makes a 180 ∘ turn,leaving horizontally. The mass of the cart is 100 kg and the jet leaves the water nozzle (of area, A=0.001 m²) with a speed of 35 m/s. There is aerodynamic drag force proportional to the square cart speed, FD = kUcart , with k=2.0Ns²/m² . (a) Derive an expression for the acceleration of the cart. This should be a function of the cart speed, U cart , and the other given parameter
