Question

Please Help ASAP A basketball player shoots a basketball with an initial velocity of 15 ft/sec. The ball is released from an initial height of 6.5 feet.
The function h(t) = -16t^2 + v0t + h0 models the height, in feet, of an object after t seconds. v0 is the initial velocity of the object, and h0 is the initial height of the object.

Part 1: Write a function that models the height of the basketball. Use your function to answer Parts 2-4.

Part 2: How long does it take for the basketball to hit the ground? Round your answer to the nearest hundredth. Show all of your work.

Part 3: When does the basketball reach its maximum height? Round your answer to the nearest hundredth. Show all of your work and explain your answer.

Part 4: What is the maximum height of the basketball? Round your answer to the nearest hundredth. Show all of your work and explain your answer.

Answer 1

Part 1: the function would be

h(t)= -16t^2+15t+6.5

Part 2: using the same steps it stated on the calculator

x=1.26

Part 3: by using t= -b/(2a) 15 as b and -16 as a  makes it

t= 15/32

Part 4: You then put 15/32 in for t in the equation making the maximum height

10.02

IDK IF THIS IS RIGHT BUT IVE SPENT ALL DAY ON THIS
