1- A block of mass M = 4 kg, initially at rest, (v = 0) is pushed a distance d = 2 m along a frictionless horizontal surface by a constant force F= 20 N directed at an angle 0 = 37 below the horizontal, see the figure. (a) Determine the work done on the block by the applied force. Write the work done by the gravitational force and by the normal force. (b) Determine the kinetic energy and the speed of the block at the end of this displacement. (sin37 = 0.6, cos37 = 0.8). 1- A block of mass M = 4 kg, initially at rest, (v = 0) is pushed a distance d = 2 m along a frictionless horizontal surface by a constant force F= 20 N directed at an angle 0 = 37 below the horizontal, see the figure.
