At a time t seconds after it is thrown up in the air, a tomato is at a height of f(t) = -4.9t^2 + 25t + 3 meters.
(a) What is the average velocity of the tomato during the first 1.7 seconds? Include units.
I know the units are m/sec but I can't get the average velocity!
(b) Find the instantaneous velocity of the tomato at t = 1.7. Include units.
It's 8.34 m/sec.
(c) What is the acceleration at t = 1.7?
(d) How high does the tomato go?
(e) How long is the tomato in the air?
I can't get this!! _______ sec
I'm so lost. Thank you =)
