how high up is a 3 kg object that has 300 joules of energy?

Answer 1

To calculate the height of a 3 kg object with 300 joules of energy, we can use the formula for gravitational potential energy:

Potential Energy = mass x gravity x height

300 J = 3 kg x 9.8 m/s^2 x height

Solving for height:

height = 300 J / (3 kg x 9.8 m/s^2)
height = 300 J / 29.4 kg*m/s^2
height = 10.2 meters

Therefore, the 3 kg object is 10.2 meters high.
