Question

object of mass 16Kg is at a certain height above the ground . If

the potential energy of the object is 580J . Find the height at which the

object is with respect to the the ground. Given g=10ms-2​

Answer 1

Answer:

3.625

Explanation:

potential energy = mgh

580 J = 16×10×h

580 J = 160 h

h = 580 /160

h = 3.625

Answer 2

Answer:

An object of mass 16kg is at a certain height above the ground. If the potential energy of the object is 580 J, the height of the object with respect to the ground is  $3.62m$

Explanation:

• Potential energy is the energy stored in an object, the gravitational potential energy is due to the height of the object with respect to another body

• For a body of mass, 'm' situated at a height 'h' from the ground on the earth the gravitational potential energy is

       $PE=mgh$

where the acceleration due to gravity $g=10m/s^{2}$

From the question, we have

mass of the object $m=16kg$

the potential energy of the object $PE=580J$

so the height of the object from the ground $h=PE/mg$

$h=\frac{580}{16*10}=3.62m$
