Solve the problem.If friction is ignored, the time t (in seconds) required for a block to slide down an inclined plane is given by the formula t = where a is the length (in feet) of the base and g ? 32 feet per second per second is the acceleration of gravity. How long does it take a block to slide down an inclined plane with base a = 12 when If necessary, round the answer to the nearest tenth of a second.
