From the top of a tower \(19.6 \mathrm{~m}\) high, a ball is thrown horizontally. If the line joining the point of projection to the point where it hits the ground makes an angle of \(45^{\circ}\) with the horizontal, then the initial velocity of the ball is
- A \(9.8 \mathrm{~ms}^{-1}\)
- B \(4.9 \mathrm{~ms}^{-1}\)
- C \(14.7 \mathrm{~ms}^{-1}\)
- D \(2.8 \mathrm{~ms}^{-1}\)
