A constant force of 20. newtons applied to a box causes it to move at a constant speed of 4.0 meters per second. How much work is done in the boxin 6.0 seconds? 1) 240 joules
2) 120 joules
3) 480 joules
4) 80. joules

The work done is 480 Joules.

Option 3 is correct.

The work done  is computed as multiplication of force and displacement.

Given that,  Force = 20 N

Displacement = 4 meter per second

For 6 second,

Displacement
