141736 In a lift moving up with an acceleration of \(5 \mathrm{~ms}^{-}\) \({ }^{2}\), a ball is dropped from a height of \(1.25 \mathrm{~m}\). The time taken by the ball to reach the floor of the lift is (nearly) \(\left(g=10 \mathrm{~ms}^{-2}\right)\)

141737 A bullet moving with a speed of \(100 \mathrm{~ms}^{-1}\) can just penetrate two planks of equal thickness. Then, the number of such planks penetrated by the same bullet when the speed is doubled will be:
