about the above axis with kinetic energy of 183 .0 J. Find the number of revolutions the system
makes per minute.
Problem 8: What linear speed must a 0 .0511 kg hula hoop have if its total kinetic energy is
to be 0 .152 J? Assume the hoop rolls on the ground without slipping.
Problem 9: After you pick up a spare, your bowling ball rolls without slipping back toward the
ball rack with a linear speed of v = 3 .40 m/s, as shown in the ﬁgure. To reach the rack, the
ball rolls up a ramp that rises through a vertical distance of h = 0 .528 m. What is the linear
speed of the ball when it reaches the top of the ramp?
Problem 10: A m1 = 14 .4 kg mass and a m2 = 10 .7 kg mass are suspended by a pulley that
