Answer 2

The height of an object is 2 meters.

Given the following data:

• Mass of object = 50 kg

• Gravitational  potential energy (GPE) = 9,800 Joules

We know that acceleration due to gravity (g) is equal to 9.8 $m/s^2$

To find the height of the object;

Mathematically, gravitational  potential energy (GPE) is calculated by using the formula;

$GPE = mgh$

$9800= 50$ × $9.8$ × $h$

$9800 = 4900h\\\\h = \frac{9800}{4900}$

Height, h = 2 meters

Therefore, the height of an object is 2 meters.
