A 40kg box has an initial velocity of 6 m/s down a 30-degree inclined plane at an initial height of 4 meters. The coefficient of friction between the box and the ground is 0.4. [a] Calculate the box's velocity when it reaches the bottom of the inclined plane. [b] Calculate the work done by friction. [c] If you increased the angle of the inclined plane, explain how that would affect the work done by friction. Show Work!!
