Solve the below given problem:
 
A ball is thrown vertically upward with an initial velocity of \(20\ m/s\). Taking \(g = 10\ m/s^{2}\) (deceleration), find:
(i) time to reach the highest point,
(ii) maximum height reached.
 
(i) Time taken by the ball to reach the highest point \(=\) \(s\)
 
(ii) Maximum height reached  by the ball \(=\) \(m\)
 
[Note: Enter the answer upto two decimal values]
