A bowling ball of mass 7.5 kg travelling at 10 m sec-rolls off a horizontal table 1 m high. (Assume the acceleration due to gravity is 10 m sec-?, and the effects of air resistance may be ignored unless otherwise stated.) a Calculate the ball's horizontal velocity just as it strikes the floor. b What is the vertical velocity of the ball as it strikes the floor? c Calculate the velocity of the ball as it reaches the floor. d What time interval has elapsed between the ball leaving the table and striking the floor? e Calculate the horizontal distance travelled by the ball as it falls.
