Question

Calculate the work done by a man weighing 50kg in climbing up a ladder 15m high. (g=9.8m/s^2)

Answer 1

Answer:

7,350

used by w = f.s

f = m.a

Answer 2

sᴏʟᴜᴛɪᴏɴ ⤵️

Given:-

1)mass of the body =50 kg

force applied on the body =m×g

=50×9.8N

=490N

displacement of the body=15m

Formula of work :-

work =Force ×displacement

I.e W=FD

Calculating the work :-

definition of work :-

Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force.

work =Force ×displacement

therefore,work =490×15joule

=7350joule

Final answer :-7350 j or joule
