At a time $t$ seconds after it is thrown up in the air, a tomato is at a height (in meters) of $f(t) = -4.9t^2 + 30 t + 1$ m.

A. What is the average velocity of the tomato during the first 2 seconds? (Include units.)
B. Find (exactly) the instantaneous velocity of the tomato at $t = 2$. (Include units.)
C. What is the acceleration at $t = 2$? (Include units.)
D. How high does the tomato go? (Include units.)
E. How long is the tomato in the air? (Include units.)
