3. In the figure, a block slides along a track from one level to a higher level after passing through an intermediate level. The track is frictionless until the block reaches the higher level. A frictional force stops the block in a distance d. The block's initial speed is v =7.0 m/s, the difference h is 1.2m, and µ =0.50. =0- =0.60 a) Find the speed when it arrives at the higher level of the track. b) Find the stopping distance, d.
