P2 (20 Pts): The wheeled cart, shown in the following figure, rolls with negligible resistance. The cart is to accelerate to the right at a constant rate of 2.5 m/s. This is to be accomplished by programming the water jet speed, V(t), that hits the cart. The jet area remains constant at 50 mm. Find the initial jet speed, and the jet speed and cart speeds after 2.5 s and 5s. Theoretically, what happens to the value of (VU) over time? p = 999 kg/m V (t) A = 50 mm M = 5 kg 120
