1. A crane lifts a 75kg mass a height of 8 m. Calculate the gravitational potential energy
gained by the mass:

Answer:

GP.E = 5880 j

Explanation:

Given data:

Mass = 75 kg

height = 8 m

Potential energy = ?

Solution:

The formula for gravitational potential energy is

GPE = mgh

m = mass in kilogram

g = acceleration due to gravity

h = height in meter above the ground

Formula:

GP.E = mgh

Now we will put the values in formula.

g = 9.8 m/s²

GP.E = 75 Kg × 9.8 m/s²× 8 m

GP.E = 5880 Kg.m²/s²

Kg.m²/s² = j

GP.E = 5880 j

The potential energy of the crane is 5880 J.

To calculate the gravitational potential energy, we use the formula below.

Formula:

  • P.E = mgh............ Equation 1

Where:

  • P.E = Potential energy of the crane
  • m = mass of the crane
  • g = acceleration due to gravity of the crane
  • h = height of the crane

From the question,

Given:

  • m = 75 kg
  • h = 8 m
  • g = 9.8 m/s²

Substitute these values into equation 1

  • P.E = 75(8)(9.8)
  • P.E = 5880 J.

Hence, the potential energy of the crane is 5880 J.
