A crate of a mass 150 kg is lifted onto a truck 2.5 m above the ground. How much potential energy has the crate gained?
m g h = 150 * 9.8 * 2.5 in Joules
A crate of a mass 150 kg is lifted onto a truck 2.5 m above the ground. How much
potential energy has the crate gained
To calculate the potential energy gained by the crate, we need to use the formula for gravitational potential energy:
Potential Energy = mass × gravity × height
In this case, the mass of the crate is given as 150 kg, the height it is lifted is 2.5 m, and we can use the standard value of gravity as 9.8 m/s^2.
Therefore, substituting the given values into the formula:
Potential Energy = 150 kg × 9.8 m/s^2 × 2.5 m
= 3675 Joules
Hence, the crate has gained 3675 Joules of potential energy.
