Unformatted text preview: 9. A 10 kg block is set in motion up a 20 degree inclined plane with an initial speed of
8.0 m/s. With no additional forces applied, the block comes to rest after traveling
some distance up the plane. a. Calculate the change in kinetic energy of the block. b. Calculate the change in gravitational potential energy of the block. 0. Assuming the interface between the block and the plane is ﬁictionless, calculate
the distance up the surface of the plane the block will travel. d. If the coefﬁcient of kinetic friction between the block and the plane is 0.10,
calculate the distance up the surface of the plane the block will travel. lows)
