a 50kg crate is lifted to a height of 10 meters how much potential energy does the crate have after being lifted?
To calculate the potential energy of an object, you can use the formula:
Potential energy = mass * gravitational acceleration * height
In this case, the mass of the crate is given as 50 kg, the gravitational acceleration is approximately 9.8 m/s² on Earth, and the height is 10 meters. Simply plug these values into the formula:
Potential energy = 50 kg * 9.8 m/s² * 10 m
Calculating this expression:
Potential energy = 4900 kg·m²/s²
Therefore, the crate has 4900 joules of potential energy after being lifted to a height of 10 meters.
