Problems:
1. A ball is struck by a paddle ant has an initial velocity of v0 = 45 ft/s at an angle of θ= 35°, The initial height of the ball is y0= 5 ft and the initial x-position = 0
a) Fing the maximum height to which the baal will rise, and the time it take reach thius height
b) Find the total time that the ball is in flight
c) Find the velocity with which the ball strikes the ground
d) How far does the ball travel in the x-direction before it strikes the ground?
2 Cable AB is connected to a winch at A and to the railroad car at B. The winch is winding the (counter-clockwise) at a constant rate of 5 ft/s When 0 = 60°. determine
a) the velocity of the car at B and the angular velocity θ→
b) the acceleration of the car at B and the angular acceleration θ→
