Will mark brainilest and I will give 5 stars: Part A: A ball of mass ,3.5kg rolls all the way down a slope inclined at 40∘ to the horizontal, with a base of length 4.8m. How much GPE does the ball lose?

Part B: If the average frictional forces are 4.0N, work out how much work the ball does against friction.

When an object moves in uniform circular motion, the direction of its acceleration is a) in the same direction as its velocity vector. b) in the opposite direction of its velocity vector c) is directed toward the center of its circular path. d) is directed away from the center of its circular path. e) depends on the speed of the object.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

The mini-refrigerator fire was most likely caused by what type of wiring?
