Question

A mass M slides upward along a rough plane surface inclined at angle ? to the horizontal. Initially the mass has a speed V0 before it slides a distance L up the incline. The coefficient of kinetic friction between the mass and the incline is ?k. While sliding, the acceleration of the mass is: Directed upward along the incline Directed downward along the incline Determined by the force of gravity on the mass Determined by the frictional force on the mass Determined by the normal force on the mass Determined by adding the magnitudes of the frictional and gravitational forces Determined by subtracting the magnitude of the friction force from the gravitational force Determined by adding the magnitudes of the normal and frictional forces
