Step-by-step explanation:
The variable t is missing in the given equation as it should read:
β(t)= β4.92t^2 + 3.28t + 1.7
When the ball will hit the ground, h=0
β4.92t^2 + 3.28t + 1.7 = 0
Using the quadratic formula to find the solution,
t = -0.34 or 1.01
As time cannot be negative, h=0 when t=1.01s. So Ana is correct.
