A typical sneeze has a maximum speed of 40 m/s. Suppose the material emitted in the sneeze begins inside the nose at rest, 2.3 cm from the nostrils. It has a constant acceleration for the first 0.23 cm and then moves at constant velocity for the remainder of the distance.

(a)What is the acceleration as it moves the first 0.25 cm? 

(b) How long does it take to move the 2.0-cm distance in the nose? 

(c) Sketch a graph of v,(t).
