A horizontal water jet impinges against the vertical back surface of a stationary cart. After striking the surface the water stream splatters off in all directions along the surface of the plate. The diameter of the nozzle exit is 6 cm and the water jet leaves the nozzle at 20 m/sec. If the mass of the cart is 400 kg and if there is no friction between its wheels and the ground calculate the acceleration of the cart when the...

A 23-cm-diameter horizontal water jet with a speed of Vj = 20 m/s relative to the ground is deflected by a 40° cone moving to the left at Vc = 10 m/s. Determine the external force, F, needed to maintain the motion of the cone. Disregard the gravity and surface shear effects, and assume that the cross-sectional area of the water jet normal to the direction of motion remains constant throughout the flow. Take the density of water to be...

a 50-mm-diameter jet of water impacts a vane at a
velocity of 20 m/s as shown in Figure 4.78. The vane has a mass of
90 kg, and it deflects the jet through a 55° angle. The vane is
constrained to move in the direction of the incoming jet, and there
is no force opposing the motion of the vane. Determine the
acceleration of the vane when it was first released. Assume water

your boss wants you to determine if the initial velocity of the sled and the weight of the team affect its acceleration down the ramp. To solve this problem, you decide to model the situation using a cart moving down an inclined track. Write down the relationship between the acceleration and the velocity of the cart. Use that relationship to construct an instantaneous velocity vs. time graph, after an initial push, just below each of your acceleration vs. time graphs...
