John used a force of 300 N to push his younger brother in a wagon for 50m. How much work did John do?
To determine the amount of work John did in pushing his younger brother in the wagon, we can use the formula:
Work = Force x Distance
In this case, the force exerted by John is 300 N (Newtons) and the distance traveled is 50 m (meters). Plugging these values into the formula, we get:
Work = 300 N x 50 m
Now let's calculate the work:
Work = 15,000 N*m
Therefore, John did 15,000 N*m (or joules) of work in pushing his younger brother in the wagon.
