Question

a ladybug crawls vertically on a leaf. its motion is shown on the following graph of vertical position y vs time t what is the average speed of the ladybug between the times t=4s and t=7s​

Answer 1

0 m/s

Step-by-step explanation:

Answer 2

Step-by-step explanation:

The attached figure shows the position-time graph of a ladybug. We need to find the average speed of the ladybug between t = 4 s to t = 7 s.

We know that, the slope of a position-time graph gives velocity of an object. It can be given by :

`v=(y_2-y_1)/(t_2-t_1)`

In this case, the position of a ladybug at t = 4 s and at t = 7 s is the same i.e. 2 m.

It means its velocity is equal to at this time or we can say that ladybug is at rest.
