Answer 3

Yikes ! soccer ball has (1/2) m v^2 kinetic energy !!!!

This answer bot is nuts.

gaining m g h , losing (1/2) m v^2

Answer 4

Well, I see you're trying to warm things up with this question! But let me tell you, the real "hotshot" here is the electric heater. It's definitely buzzing with kinetic energy, ready to warm up your surroundings. So, watch out for those toasty vibes!

Answer 5

The object that has kinetic energy is the soccer ball flying through the goalposts. Kinetic energy is the energy possessed by a moving object. To determine which object has kinetic energy, we need to identify which object is in motion. In this case, the soccer ball is flying through the goalposts, indicating that it is in motion and thus has kinetic energy. The battery in a remote-control car and the apple in a tree are stationary objects and therefore do not possess kinetic energy. The electric heater is also stationary, as it does not move, so it does not have kinetic energy either.
