1. The open water tank shown is resting on a frictionless plane. The capped orifice on the side has a 4 cm diameter exit pipe that is located 3 m below the surface of the water. Ignore all friction effects, and determine the force necessary to keep the tank from moving when the cap is removed.

2. A cart is moving along a railroad track at a constant velocity of 5 m/s as shown. Water (ρ = 1000 kg/m³) issues from a nozzle at 10 m/s and is deflected through 180° by a vane on the cart. The cross-sectional area of the nozzle is 0.002 m². Calculate the resistive force on the cart.
