(a) What is its velocity at t = 1.00 s?

v = m/s

(b) What is its velocity at t = 2.00 s?

v = m/s

(c) What is its velocity at t = 2.5 s?

v = m/s

(d) What is its velocity at t = 4.00 s?

v = m/s

(e) Describe the shape of a graph of velocity versus time for this parcel of air.

(f) What two things must be known at a given time to predict the canister's velocity at any later time?

I am lost here, I've been working on this for hours!

During those hours, have you tried using the equation

V(t)= Vo + a*t ,

where Vo is the initial velocity and a is the acceleration rate?
