a young man exerted a force of 9,000 newtons on a stalled car but was unable to move it. how much work was done?
Work = Forcedistance
Although there was a force, there was no distance.
Work = Force0 = 0 Joules, or no work
The work done by a young man that was unable to move a car when exerted a force of 9000 N is zero.
According to definition of work, we have:
\(W = F*d*cos(\theta)\)
Where:
F: is the force acting on the object
d: is the displacement
θ: is the angle between the force and displacement
The young man exerted a force of 9000 N, but since he was unable to move it, the displacement is zero, so the work done is:
\(W = F*d*cos(\theta) = 9000 N*0*cos(\theta) = 0\)
Therefore, the work done is zero.
