Harrison is correct because the 305 in the actual problem is greater than the 300 in the estimate and 57872 is less than 60000. Harrison arrived at his prediction by rounding to the nearest ten thousand and nearest hundred.
Answer:
t = 2.5 s
Step-by-step explanation:
Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :

The above equation is a quadratic equation. The general equation is :

Here, a = 16, b = 38.8 and c = 3
The solution of quadratic equation is given by :

So, at t = 2.5 s the balloon is in air.
