if friction is ignored, the time t(inseconds) required for a block to slide down an inclined plane (see the figure) is given by the formula t=square root of 2a\g sin() cos() 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) angle=30 degrees (b)angle=45 dgrees and (c) angle=60 degrees
what do I have to do is it just plugging in the numbers?
