Math Problem Statement
A basketball thrown from the edge of the court to the goal shooter is described by the formula h = −t 2 + 6t + 1, where h is the height of the basketball in metres after t seconds. a. What was the height of the ball when it was first thrown? b. What was the height of the basketball after 2 s? c. Show that the ball was first at a height of 6 m above the ground at 1 second. d. During which time interval was the ball above a height of 9 m? e. Plot the path of the basketball. f. What was the maximum height of the basketball during its flight? g. How long was the ball in flight if it was caught at a height of 1 m above the ground on its downward path?
