A 5.40 kilogram block is set into motion up an inclined plane with an initial speed of v0 = 8.10 m/s. The block comes to rest after traveling 3.00 meter along the plane, which is inclined at an angle of 30.0 degree to the horizontal.
(a) For this motion, calculate the change in the block kinetic energy.
J
(b) For this motion, calculate the change in potential energy of the block-Earth system.
(c) Calculate the frictional force exerted on the block?
N
(d) Determine what is the coefficient of kinetic friction?
