Question

8. The graph above shows the motion of a cat. What is the cat's average velocity during the time interval

0.0-20.0 s?

Answer 1

The average velocity of the cat is determined as 0.69 m/s.

How to calculate the average velocity of the cat?

The average velocity of the cat is calculated by applying the following formula as shown below.

Average velocity = total displacement / total time of motion

The total distance of the curve between 0 and 20 s is calculated as;

D = ¹/₂ (5)(1) + (5 x 1) + ¹/₂ (5)(2) + ¹/₂ (5)(0.5)

D = 13.75 m

The average velocity of the car is calculated as follows;

v = (13.75 m ) / (20 s)

v = 0.69 m/s

So the average velocity of the cat for the time period is 0.69 m/s.
