For first marble, \(h_1 - \frac{1}{2} g / 16 - 8 g\)
For Second marble, \(h_2 - \frac{1}{2} g / 9 - 4.5 g\)
For third marble, \(h_2 - \frac{1}{2} g \times 4 - 2g\)
For fourth marble, \(h_c - \frac{1}{2} g \times 1 - 0.5 g\)
\ \ \(h_1 - h_2 \quad 8g - 4.5g \quad 3.5g\) = 35 m .
\(h_2 - h_3: \quad 4.5g - 2g \quad 2.5g \quad 25m\) and \(h_3 - h_4 \quad 2g - 0.5g \quad 1.5g \quad 15m\) .
