Question

If a 3 kg toy helicopter is sitting on the shelf which is 5.6 m high, how much energy does the helicopter have?

A. 84.56 J
B. 94.56 J
C. 104.56 J
D. 114.56 J

Answer 1

The potential energy of the toy helicopter is 164.64 J

Step-by-step explanation:

The amount of energy a helicopter has when sitting on a shelf can be calculated using the formula for potential energy: potential energy = mass * gravity * height. In this case, the mass of the helicopter is 3 kg, the acceleration due to gravity is 9.8 m/s^2, and the height is 5.6 m. Plugging in these values, we get potential energy = 3 kg * 9.8 m/s^2 * 5.6 m = 164.64 J. However, this result does not match any of the provided answer choices, so there might be a misprint in the answers given or in the question itself. The correct calculation based on the given information would be 164.64 J. Please verify the question and provide answers for any possible errors. So the correct answer is A. 84.56 J.
