a 17kg box is sitting on a shelf with the potential energy of 350 J how high is the shelf
P.E. = m * g * h
350 J = 17 kg * 9.8 m/s^2 * h
h is in meters
To determine the height of the shelf, we can use the formula for gravitational potential energy:
Potential Energy = mass * gravitational acceleration * height
In this case, the mass of the box is 17 kg, and the potential energy is given as 350 J. The gravitational acceleration on Earth is approximately 9.8 m/s^2.
We can rearrange the formula to solve for height:
height = Potential Energy / (mass * gravitational acceleration)
Substituting the given values:
height = 350 J / (17 kg * 9.8 m/s^2)
Calculating the result:
height ≈ 2.13 meters
Therefore, the height of the shelf is approximately 2.13 meters.
