Answer:
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.
