While hiking, Marek throws a rock off a cliff that is roughly 10 meters above a lake. This situation is modeled by the equation h = -4.9t^2 + 10, with h representing the height in meters and t the time in seconds. If
you were to set up a table to determine when the rock hits the water, what would be a reasonable scale for the range? (1 point)

Solve -4.9t^2 + 10 = 0 → t^2 = 10/4.9 ≈ 2.041 → t ≈ 1.43 s, so a range up to 2 seconds is reasonable.
