To determine how much potential energy has been converted to kinetic energy at point B, we need to know the total potential energy at the top of the ramp. Assuming point A (the top of the ramp) has an initial potential energy \( PE_{\text{initial}} \) and is converted to kinetic energy as the ball rolls down the ramp:
1. If point B represents a distance halfway down the ramp, it means that half of the potential energy has been converted to kinetic energy at point B.
2. If we assume, for example, that the total potential energy at point A is 100 J, then at point B, half of that energy (50 J) would have been converted to kinetic energy.
Without knowing the exact total potential energy at the top, let's consider the possible answers provided. If we were to assume maximum potential energy at point A is 100 J:
- At point B (halfway), the conversion to kinetic energy would be 50 J.
Thus, the answer can be deduced as follows:
**The answer is: C 50 J.**
