A body falls for 5 s from rest. If the acceleration due to gravity of earth ceases to act, the distance it travels in the next 3 s is |
| Answer» HOPE this helpsHere is you're answer...............Explanation:Initially the body STARTS its motion from rest therefore u=0. Let JOURNEY be A when a acceleration of earth is acting on the body time =5 seconds let's find v v=u+at =0+9.8×5=49m/s When acceleration stops acting the velocity of the body is 49m/s. Now the distance traveled by the body in next 3s S = utInitially the body starts its motion from rest therefore u=0. Let journey be A when a acceleration of earth is acting on the body time =5 seconds let's find v v=u+at =0+9.8×5=49m/s When acceleration stops acting the velocity of the body is 49m/s. Now the distance traveled by the body in next 3s S=ut+ = 49 x 3 + x 0 x = 49 x 3 = 147 | |
