An aeroplane is moving with a horizontal velocity u at a height h above the ground. If a packet is dropped from it. The speed of the packet when it reaches the ground will be
- \(\left(u^{2}+2 g h\right)^{1 / 2}\)
- \((2 \mathrm{gh})^{1 / 2}\)
- \(\left(u^{2}-2 g h\right)^{1 / 2}\)
- 2 gh
Answer
(A) (u^ 2 +2 g h )^ 1 / 2
