Kicking a field goal |
2007-03-13 |
|
From san:
A football player attempts a field goal by kicking the football. The ball follows
the path modelled by the equation h= -4.9^2+10t+3, where h is the height of the
ball above the ground in metres, and t is the time since the ball was kicked
in seconds.
*the ball must clear the uprights for the field goal to count. The uprights are approximately
5 m high. How long does the ball stay above 5 m in height?

Maximizing the angle to the goal mouth |

From Yogendra:
You are running down the boundary line dribbling the ball in soccer or hockey. Investigate where in your run the angle the goal mouth makes with your position is at a maximum.
