Solution

The work done by the boy can be calculated using the formula for work, which is:

Work = Force x Distance

In this case, the force is the weight of the block, which can be calculated using the formula:

Weight = Mass x Gravity

Given that the mass of the block is 1 kg and the acceleration due to gravity is 9.8 m/s², the weight of the block is:

Weight = 1 kg x 9.8 m/s² = 9.8 N

Therefore, the work done by the boy in lifting the block by 1 m is:

Work = 9.8 N x 1 m = 9.8 Joules
