A body dropped from a height \( h \) with initial velocity zero, strikes the ground with a velocity \( 3 \mathrm{~m} / \mathrm{s} \). Another body of same mass dropped from the same height \( h \)
P with an initial velocity of \( 4 \mathrm{~m} / \mathrm{s} \). The final velocity of

W second mass, with which it strikes the ground is
(a) \( 5 \mathrm{~m} / \mathrm{s} \)
(b) \( 12 \mathrm{~m} / \mathrm{s} \)
(c) \( 3 \mathrm{~m} / \mathrm{s} \)
(d) \( 4 \mathrm{~m} / \mathrm{s} \).
