potential energy of the object is 240 J, find the height at which the
object is with respect to the ground. Given, g = 10 m s-2​ . NO SPAMMERS

Answer 1

Answer:

the height at which the object is with respect to the ground is 4 meter.

Explanation:

Given,

An object of mass 6 kg is at a certain height above the ground. the

potential energy of the object is 240 J.

To find: the height at which the object is with respect to the ground.

Solution:

Potential energy is defined as the energy possessed by body by virtue of position and configuration.

or, P.E = mgh

here, m = 6 kg, P.E = 240 J , g = 10 m/s^2

Substituting the values,

240 = 6 * 10 * h

or, h = 240 / 60

or, h = 4 m

Therefore, the height at which the object is with respect to the ground is 4 meter.

Answer 2

Given

• Mass (m) = 6 Kg
• Potential energy (P.E) = 240 J
• Acceleration due to gravity (g) = 10 m/s

To find

• Height (h)

Solution

• P.E = mgh

Substituting we get :-

• 240 = (6)(10)(h)
• 240 = 60h
• h = 240/60
• h = 24/6
• h = 4

Hence, the height at which the object is with respect to the ground is 4 m
