Skill Practice 4 A quarterback throws a football with an initial velocity of 72 ft/sec at an angle of 25 ° . The height of the ball can be modeled by h ( t ) = − 16 t 2 + 30.4 t + 5 , where h ( t ) is the height (in ft) and t is the time in seconds after release. a. Determine the time at which the ball will be at its maximum height. b . Determine the maximum height of the ball. c. Determine the amount of time required for the ball to reach the receiver’s hands if the receiver catches the ball at a point 3 ft off the ground.

Please help I'm a working mom trying to help my son last minute (6th grader)! Need help with the blank ones and check the ones he got with full calculation so we can use it to study! Especially the mixed number fractions cause I'm rusty. Thanks in advance!
