a)

i) At t= 1, what is the height? At t= 2, what is the height? What is the change in height during that 1 second? The average velocity is "change in height divided by change in time.

ii) At t= 1, what is the height? At t= 1.5, what is the height?

iii) At t= 1, what is the height? At t= 1.1, what is the height?

iv) At t= 1, what is the height? At t= 1.01 (I am sure it is NOT supposed to be "1.101") what is the height?

v) At t= 1, what is the height? At t= 1.001 what is the height?

vi) either make a "guess" at the limit, as the second t goes to 1 or take the derivative of the height function.
