Detailed Solution

The work done is more in the case of a bicycle.
The work done is defined as the product of force and displacement of the body.
We know the equation of work done as,

\Rightarrow W = F \times s

Here,

W, F,

and

s

represents work done, force and displacement respectively.
Given that, the truck does not move at all when pushed by a boy. But a bicycle moves through a certain distance. This is because the truck is heavier than a bicycle. It requires more force to push a truck than a bicycle. As the force does not displace a truck, the displacement of the truck is zero, and hence the work is done. Thus, the work done is more in the case of a bicycle.
