A boy throws a stone vertically in the air with an initial speed of 40 m/sec.at the instant the stone is thrown,a monkey at the top of a tree h m high falls freely.How long will it take for the stone to hit the monkey if they meet at a point mid way between the ground and the top of tree?
Using 1st equation of motion you can get the value of time and this will be 2.0 secs for height "h" but we wanna find for "h/2" just divide your time by 2 also. You will get your answer.
