Chapter 4, Problem 111P
The wheeled cart shown rolls with negligible resistance. The cart is to accelerate to the right at a constant rate of 2.5m/s2. This is to be accomplished by “programming” the water jet speed, V(t), that hits the cart. The jet area remains constant at 50 mm2. Find the initial jet speed, and the jet speed and cart speeds after 2.5 s and 5 s. Theoretically, what happens to the value of (V – U) over time?
