A ball is dropped on the floor from a height of \( 10 \mathrm{~m} \). It rebounds to a height of \( 2.5 \mathrm{~m} \). If the ball is in contact with the floor for \( 0.01 \mathrm{sec} \), the average acceleration during contact is
[BHU 1997; CPMT 1997]
(a) \( 2100 \mathrm{~m} / \mathrm{sec}^{2} \) downwards
(b) \( 2100 \mathrm{~m} / \mathrm{sec}^{2} \) upwards
(c) \( 1400 \mathrm{~m} / \mathrm{sec}^{2} \)
(d) \( 700 \mathrm{~m} / \mathrm{sec}^{2} \)
