A person pulls a block 3 m along a horizontal surface by a constant force F=20 N. Determine the work done by force F acting on the block.

Sagot :

Take into account that the work done is given by the following formula:

[tex]W=F\cdot d[/tex]

where,

F: applied force = 20N

d: distance = 3m

Replace the previous values into the formula for W:

[tex]W=(20N)(3m)=60J[/tex]

Hence, the work done by the person is 60J
