A body dropped gently from a height h takes time t to reach the ground. Velocity of this body at theheight h/2 is:A) gtB) gt/2C) gt/√2D) gt/4E) gt^2/2 |

Answer» a) GT Solution :- In solving a numerical physics, please dont be CRAZY in FINDING the answers only, The more you FEEL ,the more you know Physics. As the ball is dropped gently the it must have (u=0), According to the equation of motion, at height H/2 , distance travelled=H/2,so v² = 2gH/2=gH V=√(gH ) and DIRECTION of velocity is in the direction of acceleration due to gravity. |
