Question

chapter was this plz answer my previous question​

Answer 1

Answer:

Answer ➪

Mass of body M = 0.5kg

Potential energy P.E = 100J

Force of gravity on 1 kg is 10 N

→ F = mg

→ 10 = 1 × g

⇒ g = 10m/s²

change in Potential energy

= mg( h1 - h2 )

= mg( h - 0 )

= mgh

Height ⇒

100 = mgh

h    = 100 / (0.5 × 10)

h    = 20m
