4. A force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?

42 Joules

Explanation:

Given that a force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?

The parameters given are:

Distance covered = 7.0 m

The force = 6.0 m

The formula for work done is the product of force and distance. That is,

Work done = force × distance

Where work done is the same as energy.

Energy = force × distance

Energy = 6 × 7

Energy = 42 Joules.

Therefore, the energy gained by the block is 42 Joules.
