The path of the ball for many golf shots can be modelled by a quadratic function. THe path of a golf ball hit at an angle of about 10 degrees to the horizontal can be modlled by the function
h= -0.002d^2 + 0.4d
where h is the height of the ball, in meters, and d is the horizontal distance the ball travels, in meters, until it first hits the ground.
a) what is the maximum height reached by the ball?
b) what is the horizontal distance of the ball from th egolfer when the ball reaches its maximum height?
c)what is the distance does the ball travel horizontally until it first hits the ground?
if anyone can help, it would be fantastic!
