Chapter 6, Problem 1CQ

A cyclist goes around a level, circular track at constant speed. Do you agree or disagree with the following statement? “Since the cyclist’s speed is constant, her acceleration is zero.” Explain.

Expert Solution & Answer

To determine

To find whether there is any acceleration for the given case.

Answer to Problem 1CQ

No. There is a presence of acceleration, which is called as centripetal acceleration.

Explanation of Solution

Consider any object moving in a circle at a constant speed. The motion obtained by that object is called as uniform circular motion. To obtain such a motion, acceleration must be given in the direction of the center of the circle.

This kind of acceleration is called as centripetal acceleration, which acts towards the center.

Conclusion:

Thus, there is an existence of acceleration in the given case.

. Is it possible for a body moving on a circular track to have zero acceleration? Explain vividly if Yes or No

7. A man runs around a circular track of 800 meters radius for 30 seconds, starting at a point directly to the right of the center and goes in a counterclockwise manner. He goes 5 meters per second for the first 15 seconds, runs 90 meters for the next 6 seconds and then 180 meters for the rest of the course. (a) What was his average speed? (b) What was his average velocity? (c) What was his displacement from the starting point? (d) What wll be hls total displacement upon returning to the starting polnt.

Starting from rest, the motorboat travels around the circular path, p = 50 m, at a speed v = (0.8t)m/s, where t is in seconds. a) Determine the magnitude of the boat's velocity when it has traveled 25 m. b) Determine the magnitude of the boat's acceleration when it has traveled 25 m.
