Is that just the question? I can help you out but it doesn’t make any sense.
Five names for -214 are negative 214, drop of 214, minus 214, below 214, and taking away 214.
I’m not sure i understand your question, could you send a picture of the question ??? i want to help you out ☝
The equation only is true for objects with negligible air resistance. A feather does not have this property.
Using the equation shown:
50 = -16t^2
t^2 = 50/16 = 3.125
t = sqrt(3.125) = 1.77 seconds
