Question
A bird flies from the ground to a height of 200 m. If the bird has a mass of 1.5 kg, how much gravitational potential energy does it gain?A.550 JB.1960 JC.300 JD.2940 J
Solution
The gravitational potential energy (PE) can be calculated using the formula:
PE = mgh
where: m = mass = 1.5 kg g = acceleration due to gravity = 9.8 m/s² (approx) h = height = 200 m
Substituting these values into the formula, we get:
PE = 1.5 kg * 9.8 m/s² * 200 m = 2940 J
So, the bird gains 2940 J of gravitational potential energy. Therefore, the correct answer is D.2940 J.
