## Homework Statement

A body is moving on an inclined plane which has a slope of 30

^{o}. When the body is h=1,5m above the surface it has a velocity of v

_{o}=3 m/s. At the bottom of the plane it bounces elastically and starts moving upwards. Find the height it reaches, when the coefficient of frictions is μ=0.5, g=9.8 m/s
