Solve the all parts of given question:
Question: A 35 kg block slides down a ramp which is inclined at an angle of 20 degrees up from the horizontal. The block and the ramp have a coefficient of kinetic friction of 0.20. The top of the ramp is 2.8 m above the ground.
Part A: How much energy was lost to friction as the block slide down the ramp?
Part B: What is the final speed of the block when it reaches the bottom of the ramp?
I would really appreciate some help for above question.
