bowling ball of mass 7.5 kg travelling at 10 m/s rolls off a horizontal table 1.0 m high. (Assume the acceleration due to gravity is 9.80 m/s2, 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.
