Question: The top of a chute whose length is 12 meters is 3 meters vertically above its lowest point. A parcel of mass 1.6 Kilogram slides from rest from the top of the chute and reaches the lowest point with a speed of 5 meters per second. Calculate, for the the parcel:

(A) The gain in Kinetic Energy.
(B) The loss in Potential energy.
(C) The Work done in overcoming the frictional resistance.
(D) The average value of this resistance (force of friction).

Homework Statement


Homework Equations
