Question

A magnetic crane lifts a mass of mass 2000 kg through a vertical height of 50 m. Calculate the work done by the crane. [g=10m/s2]

Answer 1

change some digits instead of 30 write 50 and work according

Answer 2

Answer: Mass:2000kg

height: 50m

g=10m/s

To find the work done, use the formulae

P.E= mgh

=2000×50×10

10,00,000 J

Explanation:  we have to find the potential energy of the magetic crane.
