a stone is released from the top of the tower to the surface of the earth calculate its final velocity just before touching the ground |
|
Answer» u = Initial velocity of the stone = 0 m/s v = FINAL velocity of the stone s = Height of the stone = 19.6 m G = Acceleration DUE to GRAVITY = 9.8 ms−2 ∴ v 2 − 02 = 2 × 9.8 × 19.6 ⇒ v 2 = 2 × 9.8 × 19.6 = (19.6)2 ⇒ v = 19.6 ms−1 Read more on Sarthaks.com - https://www.sarthaks.com/9589/stone-released-from-tower-height-calculate-its-final-velocity-just-before-touching-ground |
