Consider an object of mass m=2.8kg sliding on a rough
horizontal surface. The object has a
speed vA=3.8m/svA=3.8m/s at point A, and it slows down
until it stops at point B, 8.8m ahead of A.
Part A - Determine the work done by the friction force on
the object between point A and point B.
Part B - If a horizontal force of magnitude F=13.2N
acted on the object in the direction of its motion from A to B,
what would the speed of the object at point B be?
