A jet of water (20◦C) impinges on a turbine blade that is translating at constant velocityU= 5 m/s. The velocity of the jet relative to the fixed nozzle of 12 cm2cross section isVj= 25 m/s. The blade turns the jet so that it makes an angleθ= 150◦measured counterclockwise from the positive x-axis. Taking into account the weight of the 150 N blade, butneglecting the weight of water on the blade, calculate:

(a) the horizontal and
(b) vertical components of force required to maintain constant blade speed.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
