Chapter , Problem 12(choose chapter or problem)
In Fig. 11-35, a solid brass ball of mass 0.280 g will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R ! 14.0 cm, and the ball has radius r - R. (a) What is h if the ball is on the verge of leaving the track when it reaches the top of the loop? If the ball is released at height h ! 6.00R, what are the (b) magnitude and (c) direction of the horizontal force component acting on the ball at point Q?
