1.	When a ball is thrown up vertically with velocity v_(0) it reaches a maximumheight ofh. when the ball reaches to triple t he maximum height. The velocity with which the ball was thrown is:
Answer» `3v_(0)` `9v_(0)` `sqrt(3)v_(0)` `2v_(0)` Solution :`V^(2) - U^(2) = 2AS` Here ` u = v_(0), s = h, v = 0 , a = - g` `0^(2) - v_(0)^(2) - 2 (-g)h` `:. v_(0)^(2) = 2gh""i.e., v_(0)^(2) prop h` i,e.,`v_(0)^(2) prop 3h` `(v'_(0)^(2))/(v'_(0)^(2))= (3h)/(h) = 3 ` `:. v'_(0)^(2)= 3 v_(0)^(2) ` `:. v'_(0) = sqrt(3) v_(0)`
