12. A baseball is hit by a bat and given a velocity of 40.0 m/s at an angle of 30.0 above the horizontal. The height of the ball above the ground upon impact with the bat is 1.0 m. [6 marks]

(a) What maximum height above the ground does the ball reach?

(b) When the ball is hit, ball's trajectory is directly at the centre fielder. If she begins running at the moment the ball is hit and catches the ball when it is still 3.0 m above the ground, how long does she run before catching the ball?
