How do i calculate (a) Ep of 1100,310m (b)then calculate the Ep when it is 50m above not 310m
To calculate the potential energy (Ep) of an object, you need to know its mass, acceleration due to gravity, and its height above a reference point.
(a) To calculate the Ep of an object at a height of 310m, you need to multiply the object's mass (a) by the acceleration due to gravity (g) and then multiply the result by the height (h). The formula for calculating Ep is:
Ep = m * g * h
First, determine the mass (m) of the object. Let's assume the object has a mass of 1100 kg.
Next, you need to know the acceleration due to gravity (g), which is approximately 9.8 m/s^2 on Earth.
Finally, calculate the Ep by multiplying the mass by the acceleration due to gravity and the height:
Ep = 1100 kg * 9.8 m/s^2 * 310 m
Calculate the multiplication:
Ep = 107,720,000 Joules
Therefore, the potential energy (Ep) of the object at a height of 310m is 107,720,000 Joules.
(b) Now, let's calculate the Ep when the object is 50m above instead of 310m.
Using the same mass and acceleration due to gravity, plug in the new height (h) into the formula:
Ep = 1100 kg * 9.8 m/s^2 * 50 m
Calculate the multiplication:
Ep = 539,000 Joules
Therefore, the potential energy (Ep) of the object at a height of 50m is 539,000 Joules.
