Assignment:
When a ball is thrown, its height in feet h after t seconds is given by the equation
h = vt – 16t^2.
where v is the initial upwards velocity in feet per second. If v = 9 feet per second, find all values of t for which h = 1. Do not round immediate steps. Round your answer to 2 decimals.
If there is more than one answer, indicate with “or”.
Provide complete and step by step solution for the question and show calculations and use formulas.
