Marshall applies a constant force of 20N to a box and causes it to move at a constant speed of 4m/s. Show that the work he does in moving the box in 6s is 480J.
To calculate the work done by Marshall in moving the box, we can use the formula:
Work = Force × Distance
In this case, we know the force applied by Marshall is 20N and we need to find the distance the box moves in 6s.
Given that the box is moving at a constant speed of 4m/s, we can use the formula:
Distance = Speed × Time
Substituting the values, we have:
Distance = 4m/s × 6s = 24m
Now we can calculate the work done:
Work = 20N × 24m = 480J
Therefore, Marshall's work in moving the box in 6s is 480J.
