Question

The gravitational potential energy stored in a box of weight 150 kgf is 1.5 × 10⁴ J. Find the height of the box. Take 1 kgf = 10 N​

Answer 1

Answer:

10 m

Explanation:

P.E= mgh

1.5*10 power 4= 150*10* h

h= 1.5*10 power 4/1500

h=10 m

Answer 2

Gravitational potential energy = U = mgh

$1.5 \times× 10^410$

J = 150 kgh$\times× h$

$1.5 \times× 10^410$

$J = 150 \times× 10 N \times× h$

$h = (15 \times× 1000) \div÷ 1500$

$h = 10 m$

Thank you :)
