Question

the gravitational potential energy stored in a box of weight 150kgf is 1.5×(10)4 J. Find the height of the box . take 1 kgf =10n​

Answer 1

P.E=1.5*(10)^4

    =1.5*10000

    =15000 J

mg= 1500 N

P.E=mgh

15000=1500*h

h= 15000/1500

h=10 meter

Answer 2

Answer:

10m

Explanation:

P.E=m×g×h

Given m×g=150 kgf=150×9.8 N.

14700=150×9.8×h

h=14700/(150×9.8)

h=10m.
