See the figure. a If friction is ignored, the time t (in seconds) required for a block to slide down an inclined plane is given by the function t1u2 = 7 2a g sin u cos u where a is the length (in feet) of the base and g 32 feet per second per second is the acceleration due to gravity. How long does it take a block to slide down an inclined plane with base a = 10 feet when: (a) u = 30? (b) u = 45? (c) u = 60?
