Question

A force of 6.0 Newton’s 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.

Answer 1

42J

Step-by-step explanation:

Given parameters:

Force applied = 6N

Distance moved = 7m

Unknown:

Amount of energy gained by the block = ?

Solution:

The amount of energy gained by the block is the same as the work done on the block.

The work done is the force applied to move the block through a distance;

Energy gained = force x distance = 6 x 7 = 42J
