Question

calculate the mass of the body which is lifted to height 15 m above the ground , PE stored in the body is 225 joule​

Answer 1

Answer:

here,

height of the man:15m

Potential energy:225j

Gravity:9.8m/s^2

mass of the man=?

we know,

P.E=m.g.h

225 =9.8×15×m

m=225/147

m=1.53

✓mass of the man is 1.53kg

Answer 2

Answer:

The mass of the body is 1.5kg

Explanation:

gravitational acceleration = 10 m/s^2

height = 15m

PE = 225j

Potential Energy = mgh (mass * gravity * height )

mass = PE/gh

mass = 225/10*15

= 225 /150

= 1.5 kg

hope this helps !
