Question

It takes 40J to push a large box 4m across the floor. Assuming the push is in the same direction as the move, what is the magnitude of the force on the box?

Answer 1

Force = 10 Newtons

Step-by-step explanation:

Work is Force times Distance

W = Force*D

The work in this case is 40 Joules (1 Joule = 1 kg*m^2/s^2)

We can write:

40 kg*m^2/s^2 = Force*(4m)

Force = (40 kg*m^2/s^2)/(4m)

Fprce = 10 kg*m/s^2

1 Newton is 1 kg*m/s^2

Force = 10 Newtons
