ll TEW ? 8:18 PM 49% Retake Done Rotate S Undo 3. A 10 kg block is dragged by a 40N applied force, which makes an angle of 300 with a horizontal, The coefficient of friction of the surface is µ, = 0.25. The block starts from rest and is pulled a distance of 5m. a) Calculate the work done by the applied force? b) Calculate the work done by the force of friction? c) What is the resultant work done? d) What is the final velocity of the block? Recall: work done equals change in kinetic energy
