Solution: 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 cats motion and construct a graph of t

Problem

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 cats motion and construct a graph of the felines velocity as a function of time (the figure The plot shows the cat’s velocity as a function of time. Time is measured from 0 to 7 seconds on the x-axis. The velocity is measured from 0 to 8 centimeters per second on the y-axis. The velocity decreases linearly from 0 seconds and 8 centimeters per second to 6 seconds and 0 centimeters per second and keeps decreasing at the same rate until 7 seconds.).

Find the cats velocity at = 5.0 s .

What is the cats acceleration at t = 3.0?

What distance does the cat move during the first 4.5 s?

Sketch clear graph of the cats acceleration as function of time, assuming that the cat started at the origin.

Find the cats velocity at = 8.0 s .

What is the cats acceleration at t = 6.0?

What is the cats acceleration at t = 7.0?

What total distance does the cat move from t = 0 to t = 7.5?

Sketch clear graph of the cats position as function of time, assuming that the cat started at the origin.
