Question

A 10,000 g body falls from a height of 20 m. Calculate the potential energy when it is at a height of 10 m

Answer 1

Ep = 980 J

Step-by-step explanation:

First, grams must be converted to kilograms. So, we must divide the value of the mass, by 1000.

• 
  `\boxed{(10000)/(1000)=\boxed{10kg}}` ---------- Converted to kg.

==================================================================

Data:

• Mass (m) = 10 kg
• Gravity (g) = 9.8 m/s²
• Height (h) = 10 m
• Potential Energy (Ep) = ?

Use formula:

• Ep = m * g * h

Replace:

• Ep = 10 kg * 9.8 m/s² * 10 m

Multiply operations, with units:

• Ep = 980 J

What is the potential energy?

The potential energy is 980 Joules.
