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 = 10 when 
If necessary, round the answer to the nearest tenth of a second.
A. 0.3 sec B. 1.2 sec C. 1.4 sec D. 1.1 sec
