If a rock has 376 J of potential energy when it’s held 10.1 m above the ground what is its mass? Round to the nearest tenth

Answer: 3.8 kg

Step-by-step explanation:

The formula for calculating potential energy is expressed as

Potential energy = mgh

where

m is the mass of the object

g is the acceleration due to gravity

h is the height above the ground

From the information given,

Potential energy = 376

g = 9.8 m/s^2

h = 10.1

Thus,

376 = m x 9.81 x 10.1

376 = 99.081m

m = 376/99.081

m = 3.8 kg

The mass is 3.8 kg
