Michael Jordan has a portable basketball hoop in his driveway. He has set the basket at 8 ft (2.4 m) high so he can practice dunking the ball (he’s a bit older now, so he can’t quite jump “Air” Jordan style). He slams the ball through the hoop and then hangs on to the rim. This exerts a downward force of 600 N on the front of the rim. The front of the rim is 1.1 m in front of the front edge of the portable hoop’s base. The mass of the whole portable basketball hoop is 70 kg. The center of gravity of the portable hoop is 1.0 m behind the front edge of the base. How much torque is produced around the front of the hoop base by the 600 N force Air Jordan exerts on the front of the rim? How much torque is needed to tip the hoop? What is the largest vertical force that can be exerted on the front edge of the rim before the portable hoop begins to tip?

In the Atwood machine shown below, ml = 2.00-kg and m2 = 5.60-kg. The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push that sets it into motion at vi = 2.15 m/s downward. How long will it take for mị to reach the lowest level? m1 m2
