A brick of mass 1.7 kg was pushed down a roof with an initial velocity of 1.0 m/s. The roof is inclined at 14.0o with respect to the horizontal, and the coefficient of dynamic friction between the roof and the brick is 0.8. The edge of the roof is 3.8 m from where the brick was pushed.
How fast will the brick be moving when it reaches the edge of the roof (in m/s)?
Or, perhaps, the brick will not reach the edge of the roof? In that case, how far from the edge will it stop (in m)?
