A ball is dropped vertically from a height \(h\) above the ground. It hits the ground and bounces up vertically to a height of \(\frac{h}{2}\). Neglecting subsequent motion and air resistance, its velocity \(v\) varies with the height \(h\) as:
[Take vertically upwards direction as positive.]

1. \(2P_0 - \frac{P_0V}{V_0}\)
2. \(3P_0 - \frac{P_0V}{V_0}\)
3. \(P_0 - \frac{P_0V}{V_0}\)
4. \(4P_0 - \frac{P_0V}{V_0}\)
