Two balls are dropped from different heights at different instants. Second ball is dropped 2 seconds after the first ball. If both balls reach the ground simultaneously after 5 seconds of dropping the first ball, then the difference between the initial heights of the two balls will be: \( \left(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2}\right) \)
- (1) \( 58.8 \mathrm{~m} \)
(2) \( 78.4 \mathrm{~m} \)
(3) \( 98.0 \mathrm{~m} \)
(4) \( 117.6 \mathrm{~m} \)
