A 2000 kg truck is raised 15 m in an elevator. What is the increase in its potential energy?
GPE = mgh
Use the change in height and the above equation to find the change in energy.
490000
490000J.
To calculate the increase in potential energy, you can use the equation:
Potential Energy = mass × gravitational acceleration × height
Given that the mass of the truck (m) is 2000 kg, the height (h) is 15 m, and gravitational acceleration (g) is approximately 9.8 m/s², we can substitute these values into the equation:
Potential Energy = 2000 kg × 9.8 m/s² × 15 m
Now, let's calculate it step by step:
Potential Energy = 2000 × 9.8 × 15 = 294,000 Joules (J)
Therefore, the increase in potential energy of the truck is 294,000 Joules (J) when it is raised 15 m in the elevator.
