Question

Arianna kicks a soccer ball off the ground and into the air with an initial velocity of 42 feet per second. Assume the starting height of the ball is 0 feet. Approximately what maximum height does the soccer ball reach?

Answer 1

h(t) = -16t² + vt + h0
v = initial velocity
h0 = initial height
Your equation is
\[h(t)=-16t^2+42t\]
find the vertex to get the max height
