A player kicks a football with an initial speed of` 25 ms^( -1)` at an angle of `45^(@)` from the ground. What are the maximum height and the time taken by the football to reach at the highest point during motion ? (Take `g=10 ms^( - 2)`)

A

`h _(max) = 3. 54 m T = 9. 125 s`

B

`h _( max) = 15.625 m T = 3. 54 s`

C

`h _(max) = 15. 625 m T = 1. 77 s`

D

`h _(max) = 10 m T = 2.5 s`
