FIGURE 5-5 -A 4.00-kg block is sliding up the plane on a 30.0 degree incline as shown in Fig. 5-5. If the coefficient of kinetic friction between the block and the incline is 0.700, what will be the acceleration of the block if a 50.0-N horizontal force pushes on the block? A)4.40 m/s² down the incline B)12.5 m/s² up the incline C)0.107 m/s² down the incline D)10.8 m/s² up the incline E)3.88 m/s² up the incline

Question

The net force acting on the block includes gravitational force, frictional force, and the horizontal force. Calculating these forces and using Newton's second law gives an acceleration of 4.40 m/s² down the incline.
