Problem 7: A crate of mass m is initially at rest at the highest point of an inclined plane, which has a height of 5.9 m and makes an angle of 0 =16° with respect to the horizontal. After being released, it is found to be traveling at v = 0.85 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the crate and the plane is u, = 0.1, and the coefficient of friction on the horizontal surface is u, = 0.2. y initial Final m V h Part (a) What is the speed of the crate, in meters per second, just after it leaves the inclined plane?
