What is the speed of an apple dropped from a tree after 1.5 second? What distance will it cover during this time?Take g=10m/s² (Ans:15m/s; 11.25m) |

Answer» Let the velocity by which the Apple is MOVING me V ms. Initial Velocity of the SPEED(u) = 0 Time taken by the Apple to fall = 1.5 s. Using the GALILEO's First Equation of the motion, v - u = at ∴ v - 0 = 10 × 1.5 ⇒ v = 15 m/s. Hence, the velocity of the Apple is 15 m/s. Hope it helps. |
