Question

A package of mass 5.50 kg slides a distance 1.48 m down a long rampthat is inclined at an angle 11.8 degrees below the horizontal. Thecoefficient of kinetic friction between the package and the ramp ismu_k = 0.305.

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 2.26 m/s at the top of the ramp, whatis its speed after sliding the distance 1.48 m down the ramp?
