A block of mass m is initially at rest at the top of an inclined plane, which has a height of 4.2 m and makes an angle with respect to the horizontal. After sliding down the ramp, the brick is observed to be moving at v = 0.95 m/s at a distance d from the end of the inclined plane. The coefficient of kinetic friction between the block and the plane is , and the coefficient of friction on the horizontal surface is .
1. What is the speed of the block, in meters per second, just after it leaves the inclined plane.
