(b) A 3.00-kg block is set into motion up an inclined plane with an initial speed of 90.00 cm/s (the shown figure). The block comes to rest after traveling 3.00 m along the plane, which is inclined at an angle of 30.0 to the horizontal. For this motion determine: a) The change in the block's kinetie energy. (b) the change in the potential energy of the block-Earth 3.00 m 30.0 system.
