At a time t seconds after it is thrown up in the air, a tomato is at a height (in meters) of f(t)=−49t^2+60t+3 m.

What is the average velocity of the tomato during the first 5 seconds?

How high does the tomato go?

How long is the tomato in the air?

forgot a decimal in your function ...

t-value for the vertex of f(t) (time at the top of its trajectory) is ... then find

total time ... set f(t) = 0 and solve for t - Oct 7th 2008, 03:19 PMcwarzecha
How do you know what b and a are?
