A boy on a bicycle drags a wagon full of newspapers at 2m using 80N force. How much work has the boy done?
First let’s think of a velocity, let’s give it .8m/s,
So first calculate the distance which would be
.8m/s x 120s (2min) = 96
Put that into the work equation w=F x d
So,
W= 96 x 40 = 3,840j
Therefore the work done was
3,840 joules
To calculate the work done by the boy, we can use the formula:
Work = Force × Distance
Given that the force applied by the boy is 80N and the distance covered is 2m, we can calculate the work done as follows:
Work = 80N × 2m
Work = 160 Joules
Therefore, the boy has done 160 Joules of work.
To find out the amount of work the boy has done, we can use the formula:
Work = Force × Distance
In this case, we know that the force applied by the boy is 80N and the distance covered is 2m. Thus, we can substitute these values into the formula:
Work = 80N × 2m
Work = 160 Joules
Therefore, the boy has done 160 Joules of work.
