    Solving a word problem using a quadratic equation with irrational roots

    When a ball is thrown, its height in meters h after t seconds is given by the equation h = vt- 5t^2 Where v is the initial upwards velocity in meters per second. If v = 7 m/s, find all values of t for which h = 1 meter. Do not round intermediate steps. Round the answer to 2 decimal places. If there is more than one

    Solving a word problem using a quadratic equation with irrational roots.

    When a ball is thrown, its height in feet h after t seconds is given by the equation Where v is the initial upwards velocity in feet per second.
