Question

hi please tell me give the formula to calculate work done on an object .
2. if an engine supply 100joule of energy to a mass of 200g how height it can be lifted . g=9.8
ans 51.02​

Answer 1

Answer:

Word done = F × S

Where ,

F stands for magnitude of the force..

S stands for the displacement..

2 .

So,

100 joule is the force

Acc to P.E ,

m *g *h

Therefore ,

200/1000*9.8*x = 100

Solve for x and get your height !!
