Question

A 2-kg toy car is held at a height of 3.75 m above the floor. How much work is done

Answer 1

Answer:

work = 0

Explanation:

Let's remember that work is defined as the product of a force by a distance. Distance is the physical path displaced by the body under the action of that force.

W = F * d

where:

W = work [J]

F = force [N]

d = distance [m]

In this case, the toy is held at a height, there is no displacement from one point to another. So there is no work and this is equal to zero.

W = (2*9.81) * 0 = 0 [Joules]
