The second box is 1.323

Explanation:

mickymike92

The potential energy of the pendulum bob at position B is 1.323 J.

What is the potential energy of the box of the pendulum?

Potential energy is the energy a body has by virtue of its position or state above the ground.

  • Potential energy = mass × acceleration due to gravity × height

The mass of the bob = 0.3 kg

height above the ground = 0.45 m

acceleration due to gravity, g = 9.8 m/s^2

Potential energy = 0.3 × 0.45 × 9.8 = 1.323 J

Therefore, the potential energy of the pendulum bob at position B is 1.323 J.
