A brick of mass 2.3 kg is lifted to a height of 1.9 m. How much gravitational potential energy is added to the brick? Acceleration due to gravity is g = 9.8 m/s2.
PE = W*g*h
W = 2.3
g=9.8
h= 1.9
PE is in units of Joules

To calculate the gravitational potential energy added to the brick, we can use the formula:
Gravitational Potential Energy (PE) = mass (m) x gravity (g) x height (h)
Given:
mass of the brick (m) = 2.3 kg
acceleration due to gravity (g) = 9.8 m/s^2
height lifted (h) = 1.9 m
Substituting the given values into the formula:
PE = 2.3 kg x 9.8 m/s^2 x 1.9 m
Now let's calculate the gravitational potential energy:
PE = 44.394 Joules
Therefore, the gravitational potential energy added to the brick is 44.394 Joules.
To find the gravitational potential energy added to the brick, we can use the formula:
Gravitational Potential Energy (PE) = mass (m) × acceleration due to gravity (g) × height (h)
Given:
Mass of the brick (m) = 2.3 kg
Height lifted (h) = 1.9 m
Acceleration due to gravity (g) = 9.8 m/s^2
Substituting these values into the formula, we have:
PE = 2.3 kg × 9.8 m/s^2 × 1.9 m
To calculate this, we can multiply the values together:
PE = 2.3 × 9.8 × 1.9
PE ≈ 42.33 joules
Therefore, the gravitational potential energy added to the brick is approximately 42.33 joules.
