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.

6. Bending a lens in OpticStudio or OSLO. In either package, create a BK7 singlet lens of 10 mm semi-diameter and with 10 mm thickness. Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function. Assign the…
