The formula for work is force x distance, and it is measured in joules, so the answer would be:

1.2m x 50N = 60J

60 J work does the student do on the bag.

The formula for work is as follows:-

[tex]W=F\times d[/tex]....(1)

Here, F is the force, and d is the distance moved in the direction of force.

Substitute 50 N for force and 1.2 m for distance in the equation (1) as follows:-

[tex]W=50\ N\times 1.2\ m\\\\=60\ Nm\\\\=60\ Joule[/tex]

Hence, the value of work is 60 J.
