For equations of the form h(t)= ax²+bx+c, the maximum height is given by the value -b/2a, which in this case would be -19.6/-9.8, or 2 seconds after being hit. The maximum height would be:
h(t)=-4.9(4)+19.6(2)+1=20.6 m.

h(t)=-4.9(4)+19.6(2)+1=20.6 m.

Answer:
to Fine the second use this formula. t= - b/2a. To find the maximum height use the original formula. h(t)= -4.9T^2+19.6T+1.
the seconds are 2 seconds.
The maximum height is 20.6 meters
