E. A ball falls off a table and reachesthe ground in 1 s. Assuming g = 10m/s^2, calculate its speed on reachingthe ground and the height of thetable. |

Answer» Answer: here's your solution
SOL: g = 10m/s² , TIME =1s , u = 0 By newton's first equation v = u+at v= 0 + (10×1) v = 0 + 10 v = 10m/s Now, By newton's second equation s = UT + (½ at²) s = (0×10) + (½ ×10×1) s = 0 + (½ ×10) s = 0 + 5 s = 5m Ans. speed of ball = 10m/s . Height of table from ground = 5m ------- By Enrique
