A cat walks in a straight line, which we shall call the x-axis,
with the positive direction to the right. As an observant physicist, you
make measurements of this cat's motion and construct a graph of the
feline's velocity as a function of time . (a) Find the cat's
velocity at t = 4.0 s and at 1 = 7.0 s. (b) What is the cat's acceleration
at t = 3.0 s? At = 6.0 s? At t = 7.0 s? (c) What distance does the cat
move during the first 4.5 s? From 1 = 0 to 1 = 7.0 s? (d) Assuming that
the cat started at the origin, sketch clear graphs of the cat's acceleration
and position as functions of time.
