Q. A piece of stone is released from rest from the rooftop of a building, and falls vertically under gravity. It takes 6.60 s to reach the ground. Neglect air resistance. (Acceleration: 9.81ms-2)
a) How tall is the building?
b) With what speed does the stone hit the ground?
c) If a bullet is fired vertically upwards with the speed calculated in (b), what is the maximum height that the bullet can reach?
In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 2.50 m/s at an angle of 15.5° above the horizontal. It is released 0.73 m above the floor. What horizontal distance does the ball cover ..
