Physics Problem- Work and Energy - A 5.00 kg block is released from rest on a Ramp

A 5.00 kg block is released from rest on a ramp that is inclined at an angle of 60.0° below the horizontal. The initial position of the block is a vertical distance of 2.00 m above the bottom of the ramp.
(a) If the speed of the block is 5.00 m/s when it reaches the bottom of the ramp, what was the work done on it by the friction force?
(b) If the angle of the ramp is changed but the block is released from a point that is still 2.00 m above the base of the ramp, both the magnitude of the friction force and the distance along the ramp that the block travels change. If the angle of the incline is changed to 50.0°, does the magnitude of the work done by the friction force increase or decrease compared to the value calculated in part (a)?
(c) How much work is done by friction when the ramp angle is 50.0°?

The best way to learn how to solve a Physics problem is to understand examples. NO AUDIO.
All problems are solved following the same basic problem-solving techniques: Break down the problem to identify given and unknown variables. Draw a model if needed. Identify relevant equations and concepts. Solve for the unknown variables. Evaluate equations with given variables.
Follow along as I break down the question and then use standard equations to solve the problem. FF, Pause, or Rewind as needed.
There are often multiple ways to get to the same answer, so don’t be concerned if your path is different, as long as the final answer is the same.
