d) Find the kinetic energy of the block at the end of the 10m slide. 5. The 4-kg block is now pushed by a force parallel to the incline so that the block slides 10m up the 300 frictionless incline at constant speed. a) Find the magnitude of the pushing force. Determine the work done on the block by b) the pushing force, c) the force of gravity, d) the normal force, c) all of the forces (the net force) on the block.
Find the change in the kinetic energy of the block. 6 If the speed of a particle is tripled by what factor does its kinetic enerery change 30
