A person using a lever applies 98 Newtons to lift a 20-kilogram box. They apply the force over a distance of 4 meters to lift the box a
distance of 2 meters. How much work is done? (1 point)
392 Joules
80 Joules
40 Joules
196 Joules
The work done can be calculated using the formula:
Work = Force x Distance
First, let's convert the weight of the box from kilograms to Newtons by using the formula:
Weight = Mass x Gravity
Weight = 20 kg x 9.8 m/s^2 (standard gravity) = 196 N
Now, substitute the given values into the work formula:
Work = 98 N x 4 m = 392 Joules
Therefore, the work done is 392 Joules.
