Question
A 9 kg block on a frictionless inclined plane at 40° has a cord attached to a pulley of mass 4 kg and radius 11 cm (see the following figure).
(a)
What is the acceleration of the block down the plane (in m/s2)? (Enter the magnitude.)
(b)
What is the work done by gravity (in J) to move the block 50 cm?
