A 33 kg child on a swing has a potential energy of 720 J with respect to the ground. What is the child’s height above the ground? please answer soon

h = 2.22 m

Explanation:

Using the international system, we know that the gravity of the earth is 9.8 m / s².

then, we have as data:

Use formula:

Replace:

Joules descompose:

Solve the multiply of mass and gravity:

Multiply the units. Knowing that kg * m/s² = N, so:

Simplify the Newtons (N), and it divides:

What is the child’s height above the ground?

The child's height above the ground is 2.22 meters.
