6) A 6 kg bowling ball is rolled down a smooth tube as shown with an initial speed of 2 m/s. Find the curve radius p such that the tube will experience no more than 1200 N. Neglect gravity. 6 kg vo 2 m/s Page 3 of 3

Solution

Since Centripetal Force is given by

F=mV_o²/p

=>1200 =6*2²/p

p=0.02 m or 2 cm
