I don't have the picture, so I can't pick the correct choice for point A from those options. Please either upload the image or describe the diagram (heights of the points, total energy, whether friction does work, reference height, mass if needed).
How to get the answer once I have the info:
- Find total mechanical energy E_total (e.g. from a stated initial KE or PE).
- Compute gravitational potential energy at A: PE_A = m g h_A (take h relative to the same reference used for E_total).
- Then KE at A = E_total − PE_A (minus any work done by friction or other nonconservative forces).
Example: if E_total = 100 J and PE at A = 25 J, KE_A = 100 − 25 = 75 J (one of your choices). Provide the picture or the numbers and I’ll compute it exactly.
