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 answer, use "or" to state.
