Question

f) A stone of mass 0.4 kg is projected vertically upward through a height of 1200 cm. If g = 10 ms-2

,

calculate the potential energy of the stone at the highest point​

Answer 1

Answer:

here is your answer hope this will help you

Answer 2

Answer:

48 J

Explanation:

Given:

• Mass of the stone = 0.4 kg

• Height through which it was projected = 1200 cm = 12 m

        (i.e., height at the highest point)

• Acceleration due to gravity (g) = 10 m/s²

To find:

• Potential energy (P.E)

Method to find:

$P.E = mgh$

⇒ P.E = 0.4 * 12 * 10

⇒ P.E = 48 J

Hence, the potential energy of the stone at the highest point is 48 Joules.

Hope it helps!
