A 75 kg snowboarder slides down a hill that has a vertical drop of 6.0 m and is inclined at 31owith respect to the horizontal. The initial speed of the snowboarder at the top of the hill is 5.0 m/s. The coefficient of kinetic friction between the ramp and the snowboard is 0.20.

A) Calculate the acceleration of the snowboarder

The acceleration is 3.40 m/s

B) Calculate the total work done on the snowboarder

C) Using the work-energy theorem, calculate the velocity of the snowboarder at the bottom of the hill
