Q. A 64 woman stands on a very light, rigid board that rests on a bathroom scale at each end. 1.5m left of her and 2.0m total. what is the reading on each of the scales?

Q. A solid brass ball of mass 14 g will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R = 2.7 m, 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? (b) If the ball is released at height h = 6.00R, what is the magnitude of the horizontal force component acting on the ball at point Q?
