Question

A body of mass 80kg is lifed vertically through a distance of 5.0m .Calculate the work done on the body(g=10m/s)

Answer 1

Answer:

4000 J

Explanation:

Mass = 80 kg

Gravity = 10 m/s

Force = Mass × Gravity = (80×10) N = 800 N

Distance = 5 m

Work = Force × Distance = (800×5) J = 4000 J

Answer 2

$\:$

Mass = 80 kg

Gravity = 10 m/s

Force = Mass × Gravity = (80×10) N = 800 N

Distance = 5 m

Work = Force × Distance = (800×5) J = 4000 J
