Chapter 6, Problem 32P
A 5-cm-diameter horizontal jet of water with a velocity of 30 m/s relative to the ground strikes a flat plate that is moving in the same direction as the jet at a velocity of 20 m/s. The water splatters in all directions in the plane of the plate. How much force does the water stream exert on the plate?

Q.1) Block A is connected to block B by a pulley
system as shown. The weights of blocks A and B
are 100 lbs and 70 lbs, respectively. Assume
negligible friction between the rope and all pulleys
as well as between block B and the incline and
neglect the mass of all pulleys and cables.
Determine the angle 0 required to keep the system
in equilibrium. (At least two FBDs must be drawn
