Question

calculate the height of an object following from the tall building of mass 150 kg and the potential energy is 450 J​

Answer 1

Given:

• Mass of an object, m = 150 kg

• Potential energy ,P.E = 450 J

• Acceleration due to gravity, g = 10 m/s

To be calculated:

calculate the height of an object following from the tall building?

Formula used:

Potential energy = m × g × h

Solution:

We know that,

Potential energy = m × g × h

⇒ 450 = 150 × 10 × h

⇒ 450 = 1500 × h

⇒ h = 450/1500

⇒ h = 3.33 ( approx)

Thus, the height of given object following from the tall building is 3.33 m.

Additional information:

Energy: Energy is the capacity or ability to do work.

• S.I unit of energy = joules

• Scalar quantity ( having only magnitudes )
