Calculate the wor

Work was done = Force × Displacement

Given

Force = 15 N

Displacement = 5 m

Work done = 15×5 = 75 J

The work done is 75 Joule

OR

Mass of object (m) = 10 Kg.

Height (h) = 6 m.

Acceleration due to gravity (g) = 9.8m/s²

Potential Energy of Object = mgh

= 10×9.8×6 = 98×6

= 588 J

The energy possessed by an object is 588 Joule.
