1-A block, M = 2.5 kg is pulled a distance, d = 2 m on a rough horizontal surface by a constant force, F = 20 N acting at an angle of 37 as shown in the figure. A constant friction force, f= 6 N acts on the block. (a) Find the total work done on the block. (b) What is the change in the kinetic energy of the block during this motion? How much energy lost during this motion? (c) If the block stats from rest what is its kinetic energy at the end of the 2 m displacement? (Assume, g = 10 m/s, sin37 = cos53 = 0.6, sin53 = cos37 = 0.8). NA Mg F = 20 N 1-A block, M = 2.5 kg is pulled a distance, d = 2 m on a rough horizontal surface by a constant force, F = 20 N acting at an angle of 37 as shown in the figure.
