Dynamics of Rigid Bodies

1. The body has a mass of 100 kg and is pulled up a 75 percent inclined by a force P. The coefficient of friction f is 0.25 between contacting surfaces.
a) determine the constant value of P required to bring the body from the rest to a velocity of 6 m/s in 10s

b) what value of P will then suffice to maintain that velocity?

2. A nozzle on the end of a fire hose is 20 m from a vertical wall and makes an angles of 45 degrees with the horizontal. If the stream strikes the wall at a point 8 m above the nozzle, what us the velocity of water as it leaves the nozzle?
