P1.- A high diver leaves the end of a 5.0 m high diving boardand strikes the water 1.3 s later, 3.0 m beyond the end of theboard. Considering the diver as a particle, determine: (a) herinitial velocity Vo (b) the maximum height reached, (c) thevelocity Vf with which she enters the water.
P2.- A rollercoaster moves 200 ft horizontally and then rises135 ft at an angle of 30 degrees above the horizontal. It nexttravels 135 ft at an angle of 40 degrees downward. What is itsdisplacement from its starting point?
P3.- A model rocket is launched straight upward with an initialspeed of 50 m/s. It accelerates with a constant upward accelerationof 2 m/s2 until its engines stop at an altitude of 150 m.
a) What is the maximum height reached by the rocket?
b) How long after liftoff does the rocket reaches its maximumheight?
c) How long is the rocket in the air?
