Mathematics - 9 December 2007

a major-league pitcher can throw a baseball in excess of 37.0 m/s. if a ball is thrown horizontally at this speed, how much will it drop by the time it reaches a catcher who is 17.0m away from the point of release ?

no air resistence
my teacher told me you might need to use the quadratic formula.

if you can show your work, that will be great.

1) 5x+7y= -3
2x+3y= -1

2) 2x+3y=7
8x+12y=2

3) 2x-y+3z=9
x +2z=3
3x+2y+z=10

4) A ball is thrown vertically upwards with a speed of 10ms. Find (a) the highest point it reaches. (b) the total time it is in the air.

The answer to part a i have got as 5.10m which is correct.

However i don't know how to get (b).
The answer in the back of the book for that is 2.04 seconds but i don't know how they got that. PLEASE helpppppppppppppp...
