Question

A female wedge-tailed eagle weighing 5.8 kg swoops down at 80 km/h from a height of 1798.32 m to the ground to attack a juvenile wallaby which had wandered away from the mob. What is the change in potential energy of the eagle? Select one: O A 102.32 kJ ов. 335.85 kJ Ос. 1.10 MJ

Answer 1

The energy which is associated with its position in space is potential energy.

Change in the potential energy= (mass) * (acceleration due to gravity) * ( height)

In our case mass= 5.8 kg , acceleration= 9.8 m/s^{​​​​​​}​​^{​​​​​2} height = 1798.32 meter

Change in potential energy = (5.8) * (9.8) *(1798.32)

Answer : change in potential energy = 102.32kJ
