If friction is ignored, the time t (in seconds) required for a block to slide down an inclined plane (see the figure) is given by 2a
the formulat
g sin cose
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 = 50 feet when
8 = 60°?
(Do not round until the final answer. Then round to two decimal places as needed.)
