A football player kicks a ball at an angle of `37^(@)` to the horizontal with an initial speed of `15 ms^(-1)`. Assuming that the ball travels in a vertical plane, calculate (i) the time at which the ball reaches the highest point (ii) the maximum height reached (iii) the horizontal range of the projectile and (iv) the time for which the reached (iii) the horizontal range of the projectile and (iv) the time for which the ball is in air.
