A ball is thrown upward at an angle of `45^(@)` with the horizontal and lands on the top edge of a builing that is 20 m away. The top edge is 10 m above the throwing point. The initial speed of the ball in metre/second is (take `g =10 m//s^(2)`)

A ball is thrown at a speed of 20 m/s at an angle of 30 ^@ with the horizontal . The maximum height reached by the ball is (Use g=10 m//s^2 )
