Work due to frictional resistance
= frictional force * Distance
Here
force = 10.0 N (due to friction)
Distance = 2.5 m
= frictional force * Distance
Here
force = 10.0 N (due to friction)
Distance = 2.5 m
Perhaps someone else can enlighten you on this.
Work = Force × Distance
In this scenario, the toddler is applying a force of 25.0 N to the chair over a distance of 2.5 m. However, there is also a force of friction opposing the motion, which we need to take into account. The resistance due to friction is 10.0 N.
To find the net force, we subtract the force of friction from the force applied by the toddler:
Net Force = Force applied - Force of friction
Net Force = 25.0 N - 10.0 N
Net Force = 15.0 N
Now we can use the formula to calculate the work done:
Work = Net Force × Distance
Work = 15.0 N × 2.5 m
Work = 37.5 Joules
Therefore, the work done to push the chair is 37.5 Joules.
