Answer:
The answer is very close, within the margin of error.
Step-by-step explanation:
When the ball hits the ground, h(t) will equal 0
0 = −4.92t^2 + 3.28t +1.7
Using the quadratic equation
-b ± sqrt(b^2 -4ac)
------------------------------
2a
where a = -4.92 b = 3.28 and c = 1.7
-3.28 ± sqrt(3.28^2 -4(-4.92)1.7)
------------------------------
2(-4.92)
t≈-0.342418
t≈1.00908
The answer is very close, within the margin of error.
