WebbWork, Energy, and Power Example Question #1 : Work, Energy, And Power A 2kg box slides down a ramp a distance of two meters before it reaches the ground. The ramp has an angle of 30o. The coefficient of kinetic friction for the ramp is 0.1. What is the work done by gravity on the box? Possible Answers: Correct answer: Explanation: WebbSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned.

Mathematically, it is computed using the following equation. Power = Work / time or P = W / t The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. men\u0027s gold ring with stone
