2) 200 m a A box with mass of 40kg slides down a ramp with an inclination of 0=20 for L=20 meters. The coefficient of kinetic friction is 0.4 and the initial velocity of the box is v = 6 m/s. a) Calculate the work done by the weight and frictional force between 0 and b) Use the principle of work and energy to find the final velocity of the box (V). 2) 200 m a A box with mass of 40kg slides down a ramp with an inclination of 0=20 for L=20 meters.
