The work done in moving a mass over a distance is the product of the weight of the mass and the distance, the work done in this example is

68.67 Joules

Force, Weight and Work

Given Data

Mass of the shot put = 7kg

Distance moved = 1 meter

Work Done in moving the shot put = ??

We know that the expression for the Work done is given as

Work Done = Force * Distance

Let us find the force

Force = mg

g = 9.81 m/s^2

Hence the work done

Work done = 7*9.81*1

Work done = 68.67 joules
