Compute all parts of given problemproblem a 28 kg block, Ask an Expert

Academics

Compute all parts of given problem:

Problem: A 28 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 co-efficient of kinetic friction of 0.22. The top of the ramp is 2.5m above the ground.

Part A: How much energy was lost to friction as the block slid down the ramp?

Part B: What is the final speed of the block when it reaches the bottom of the ramp?

Please, show work so I can understand the concept. Thanks.
