Problem 50P

(II) The position of a rabbit along a straight tunnel as a function of time is plotted in Fig. 2-28. What is its instantaneous velocity (a) at t = 10.0 s and (b) at t = 30.0 s? What is its average velocity (c) between t = 0 and t = 5.0 s, (d) between t = 25.0 s and t = 30.0 s, and (e) between t = 40.0 s and t = 50.0 s?

Step-by-Step Solution:

Solution:

Step 1 of 2:-

Here we need to find the instantaneous velocities and average velocities at the given time and time intervals.

a)

The instantaneous velocity at t = 10 s.

The slope is constant from t =0 to t = 20 s.

So, the slope is of the graph will provide the instantaneous velocity.

The instantaneous velocity at t = 10 s is: 0.3 m/s.

b)

At t = 30 s.

         

The instantaneous velocity at t =30 s is: 1 m/s.
