Solve the all parts of given question:
Question: A 4.50kg package slides 1.55m down a long ramp that is inclined at 11.5 m below the horizontal. The coefficient of kinetic friction between the package and the ramp is µk = 0.307.
Part A: Calculate the work done on the package by friction.
Part B: Calculate the work done on the package by gravity.
Part C: Calculate the work done on the package by the normal force.
Part D: Calculate the total work done on the package.
Part E: If the package has a speed of 2.10m/s at the top of the ramp, what is its speed after sliding the distance 1.55m down the ramp?
I need help to find the work done on the package by friction and express your answer to three significant figures.
