Question

A weightlifter lifts a 1400 N barbell 2.5 meters. Calculate the work done during the lift

Answer 1

Force = 1400N

Displacement = 2.5 m

work done = F×D

=1400×2.5

= 3500 joule

Answer 2

Answer: W = 3500 J

Explanation: Work is the product of the amount of force and the perpendicular distance or W = Fd.

W = Fd

= 1400 N ( 2.5 m )

= 3500 J
