1-An object of mass m=2kg which is initially at rest is pushed upward by a horizontal force F= soN along the incline surface as shown in the figure. The coefficient of friction between the mass and the surface is =O.5. The block traveled a distance =10m along the incline under the action of F. Determine a) Work done by the horizontal force b) Work done by the friction force c) Work done by the gravitational force d) Work done by the normal force e The acceleration of the mass f The velocity of the block after it traveled the distance d (g= 10 m/s°, = 37 ° COS37° = 0.8, sin37° = 0.6)
