Achild is riding a bike and skids to a stop. what happens to their kinetic energy?

It turns to potential energy?

We’re learning this in science and I’m pretty sure this is it

The center is basically the heart of it

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
