A 10-lb bock is resting on an inclined surface at an angle of 30°, as shown. The block is in contact with a compressed spring that has a modulus of 75lb/in. The spring has an initial compression of 6 inches that is released by cutting the restraining cords. If the coefficient of kinetic friction between the inclined surface and the block is 0.15, determine the speed of the block as it leaves the spring.
