Question

how high up is a 3.00 kg object that has 300 J of energy?​

Answer 1

Answer:

The height of the object is 10.204 meters.

Explanation:

In our case, we are dealing with gravitational potential energy. To solve this, we will use the formula:

GPE = mgh

where

GPE     is the gravitational potential energy, unit is in Newton-meter (N.m) or

          Joules (J)

m         is the mass of the object, unit is in kg

g          is the acceleration due to gravity, equivalent to 9.8 m/

h          is the height of the object, unit is in meters (m)

For the given information

m = 3.00 kg

GPE = 300 J

h = ?

Solving the problem

Let us use the formula for gravitational potential energy, we have:

GPE = mgh

Then substitute the given information, we have:

300 J = (3 kg)(9.8 m/)h

Dividing both sides of the equation by (3 kg)(9.8 m/), we have:

h = 10.204 meters

Therefore, the height of the object is 10.204 meters.

Answer 2

Answer:

The object is at a height of 10.2 m.

Explanation:

• Potential Energy: The energy possessed by an object due to its shape, configuration and position is called potential energy. The SI unit of potential energy is Joule(J).
• The formula for potential energy, P.E = mgh

        Where m = mass of the object. h = height of the object

         g = acceleration due to gravity = 9.8 m/s²

• Given data: m = 3 kg, P.E. = 300 J, g = 9.8 m/s²

                             Here we have to find 'h'.

          Putting all the values in above formula, 300 = 3 × 9.8 × h

                                                                                 h = $\frac{300}{3 * 9.8}$ = 10.2 m

      ∴ The object is at a height of 10.2 m.
