Question

If a student exerts a force of 25N on a table, the table is displaced by 3 meters, how much work was done by the student?


find its correct answer with explanation and is it correct​

Answer 1

75 joules

work = force × displacement

Student exerts a force of 25 N on a table to displace it by 3 meters.

Force = 25 N

displacement = 3 meters.

Work done = 25 N × 3 m

= 75 Nm = 75 J

The amount of work done by the student to displace a table 3 meters by exerting a force of 25 N is 75 joules.

Answer 2

Work done by the student is 75 Joules.

Given - Force and distance

Find - Work done

Solution - Work done is calculated by the formula = Force*distance

Keep the values in formula

Work done = 25*3

Performing multiplication

Work done = 75 Joules

Hence, the work done by the student is 75 Joules.
