WORK AND KINETIC ENERGY 2. A block of mass M = 4.2 kg, slides down an inclined plane of angle 0 = 30° due to the force of gravity. The block moves a distance d = 6.5 meters, parallel to the plane. There is a frictional force on the block, FF = μFN where μk = 0.53 and FN is the normal force of plane on block. The Block is released at the upper point with velocity = 0. M D = 12m M 30° Mg (Hint: fine the components of force Mg along and perpendicular to the sliding surface of the plane.) (a) O Calculate the WORK DONE on the mass M by force of gravity, Wgravity, when m has moved a distance D along the plane. (b)l Calculate the WORK DONE on M by the friction force, FF, Wfriction, when Mt has moved the distance D along the plane. (What is FN ?) Using the "Work-Kinetic Energy Theorem" find the speed on the block when it has moved the distance D.
