In the figure below, a 10 kg block is compressed 0.5 m (to point A) on a
spring that have a constant k= 4000 N/m. The block is released from rest to
slide on the track. The track is frietionless except between the points B
and C (d = 5 m) there is a friction. The block travels on the track and
raiseh = 3 m above the track level, before coming to rest momentarily at
point D. Assume g - 10 m/s", Determine the
h = 3 m
