a bicycle rider pushes a bicycle that has a mass of 1.3 kg up a steep hill. the incline is 25 degrees and the road is 275 m long. the rider pushes the bike parallel to the road with a force of 25 n. how much work is done by the force of gravity?



Answer :

The power of gravity generates work. W = -14264.6 J.

On the bike, the following is the labor that gravity does:

[tex]W_{g}=|F_{g}|*|d|*cos[/tex]

Because of the weight of the bike, gravity acts as a force.

[tex]|F_{g}|=-mgsin(24)[/tex]

Because of the direction of the motion's opposition to the direction of gravity's force, the symbol is negative.

As a result, 14264.6 J is the amount of work that the bike's gravitational force has done.

What is a force in science?

In science, the word 'force' has a precise meaning. At this level, it is completely appropriate to describe a force as a push or a pull. A force is not something that an object contains or 'has in it'. A force is exerted on one object by another. The idea of a force is not limited to living things or non-living things.
