Energy Conservation With Friction
A 0.5 kg block with an initial potential energy of 20 J slides down a frictionless track. It then continues up a second track where the coefficient of kinetic friction is $$\mu = 0.2$$. What is the maximum height the block attains on the second track?
A
3.27 m
B
4.08 m
C
3.40 m
D
2.04 m
