Question

If a toy helicopter is moving at 12 m/s, how much energy does 3kg toy have?

Answer 1

Answer:216 J Is the answer I just checked

Explanation:

Answer 2

9514 1404 393

Answer:

216 J

Explanation:

The kinetic energy is given by ...

KE = 1/2mv^2

KE = (1/2)(3 kg)(12 m/s)^2 = 216 kg·m²/s² = 216 J

The kinetic energy of the toy is 216 joules.

__

Its potential energy depends on its height.
