How much work is done when a 700 n refrigerator is lifted straight up a distance of 4 meters

The work done is 2800 Joules

Explanation:

When a force causes a body to move, work is being done on the object

by the force

Work is the measure of energy transfer when a force moves an object

through a distance

→ Work = Force × Distance

→ The SI unit for work is the joule (J)

A refrigerator of 700 N is lifted straight up a distance of 4 meters

We need to find the work done

→ The weight of the refrigerator is 700 N

→ The force = 700 Newtons

→ The refrigerator is lifted straight up 4 m

→ The distance = 4 meters

Substitute these values in the rule below

→ Work = Force × Distance

→ Work = 700 × 4 = 2800 Joules

The work done is 2800 Joules

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
