APFIVE Energy Conservation With Friction
A 0.5 kg block slides down a frictionless track from height h to height 0, then up a second track with coefficient of kinetic friction $$\mu = 0.2$$. If the block’s initial potential energy is 20 J, what is the maximum height it reaches on the second track before coming to rest?
A
3.27 m
B
2.04 m
C
3.40 m
D
4.08 m
