Question

How much work does it take to raise a `7 kg` weight `1 m`?

Answer 1

Work done is `68.6` joules

Explanation:

Work done is Force multiplied by distance. As weight is `7 kg` and distance is `1 m`, (it is assumed that force is applied against gravity `9.8 m/s^2`, as the words 'raise' and 'weight' are used)

Work done = `7*9.8*1` i.e. `68.6` joules.
