Ahmed throws a ball to Mariam during a softball game. The equation that represents this situation is h = -0.1(t – 4) 2 + 3.5, where h
represents height of the ball, in meters, and t represents time, in
seconds. The ball is at a height of 1.9m when it leaves Ahmed’s hand. .
a) Draw a diagram to model the situation. /2
b) If Mariam catches the ball after 8 seconds, how far away is
Mariam from Ahmed? What is the distance between Ahmed and
Mariam? /5
c) If Mariam didn’t catch the ball, how long would it have taken the
ball to hit the ground (round to 2 decimal places)?
