Ke = (1/2) m v^2

only one of them has a speed , v, the soccer ball

Of course if the car is moving the battery inside is also moving, but that is not the answer they want.

Well, I hate to break it to you, but the battery in a remote-control car doesn't have any kinetic energy. It's more like "stationary energy." As for the soccer ball flying through goalposts, now that's some kinetic energy in action! It's like the ball is saying, "Look at me zoom through those posts!" And sorry to disappoint you, but the apple in a tree isn't exactly a high-energy object either. Lastly, the electric heater might provide some warmth, but it's not exactly the poster child for kinetic energy. So, the answer is clear: it's the soccer ball flying through the goalposts that's got the kinetic energy going on!

bruh shut up, goofy ahh

The object that has kinetic energy in this case is the soccer ball flying through the goalposts. Kinetic energy is the energy possessed by an object due to its motion. To determine which objects have kinetic energy, you need to consider if they are in motion. In this scenario, the soccer ball is flying through the goalposts, indicating that it is moving. Movement means that the object has kinetic energy. On the other hand, the battery in a remote-control car, apple in a tree, and electric heater are not described as being in motion, so they do not possess kinetic energy in this particular scenario.

You do it yourself.
