4. 2 Kg box is pushed upward 10 m along 30 degree inclined plane with a force of 60N Parallel to the plane. The friction force between the box and the surface is 12 N. Determine a. Acceleration of the box b. Velocity of the box at the end of 10 m.( assume initial velocity as zero) c. Kinetic energy change. d. Work done by all forces acting on the box e. Work done by all forces except weight( gravitational force) f. Change of total energy of the box
