Question 879548: Hey tutors could you please help with this probelm!

Jack kicked a football. The height, h(t) in feet, of the ball t seconds is given by the quadractic function
h(t)=16t^2+64t.
a. After how many secounds does the ball hit the ground? Show how you determined your answer?
b. Does the ball reach its maximum height a t=2 seconds? Show how you determined your answer?

Jack kicked a football. The height, h(t) in feet, of the ball t seconds is given by the quadractic function
h(t)=16t^2+64t.
a. After how many secounds does the ball hit the ground? Show how you determined your answer?
When h(t) = 0
Only at t = 0
=====================
b. Does the ball reach its maximum height a t=2 seconds? Show how you determined your answer?
There's no max height, h(t) increases with t.
