141178 A rocket moves straight upward with zero initial velocity and with an acceleration \(20 \mathrm{~m} / \mathrm{s}^{2}\). It runs out of fuel and stops accelerating at the end of \(5^{\text {th }}\) sec. It reaches a maximum height and falls back to the earth. The speed when it hits the ground is (Take \(g=10 \mathrm{~m} / \mathrm{s}^{2}\) )
