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.
Discover the speeds with which Mercury and Saturn move around the sun. Does it make sense that Mercury is named after a speedy messenger of the gods, whereas Saturn is named after the father of Jupiter?
