What is the 
? Yes, I know it is a typo. But if you are too lazy to proofread your posts BEFORE you click on SEND, why should any of us exert any effort at all to help you?
\ =\ 35t\ -\ 5t^2)
is the almost proper function. I say almost because using 
as the value for one-half of the acceleration due to the gravitational force near the surface of the earth gives much more precise answer. Be that as it may, solve
for both values of
