Question

an object with 100N is raised to height 15m.Find (i) the potential energy (ii) find the new potential energy if the object raised half of the original height

Answer 1

potential energy=Force * height=100*15=1500J
new potential energy= force*(height/2)=750J

Answer 2

Hi friend,

We know that

Potential energy= mah
(F= ma)
Potential energy= f× h

P.E= 15×100

P.E= 1500 J

New p.e= F× h/2

= 1500/2

New potential energy= 750 J.

Hope this helped you a little!!!
