20. You are intrigued with the performance and safety of the new battery assisted bicycles, and are considering a purchase despite their hefty cost. Key to your decision will by the maximum speed which is suggested by the manufacturer to be 20 mph. To verify the maximum speed, you mark off 50 m on a level roadway and give the borrowed bike a go. From rest, and well in advance of your road marking, you pedal to your maximum cadence, perfectly timing your maximum speed as you cross the zero marker, and sustaining your effort through the 50 m distance, your friend standing aside and measuring 5.1 s as the elapsed time associated with your constant speed portion of the cruise. A) How does your experimental determination for your maximum speed compare to the manufacturer's suggested speed? B) You are also curious about your acceleration in the period before reaching your max speed. That part of your course being approximately one-half of the length of your marked course.

Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.

Question
Transcribed Image Text:20. You are intrigued with the performance and safety of the new battery assisted bicycles, and are
considering a purchase despite their hefty cost. Key to your decision will by the maximum speed
which is suggested by the manufacturer to be 20 mph. To verify the maximum speed, you mark
off 50 m on a level roadway and give the borrowed bike a go. From rest, and well in advance of
your road marking, you pedal to your maximum cadence, perfectly timing your maximum speed
as you cross the zero marker, and sustaining your effort through the 50 m distance, your friend
standing aside and measuring 5.1 s as the elapsed time associated with your constant speed
portion of the cruise. A) How does your experimental determination for your maximum speed
compare to the manufacturer's suggested speed? B) You are also curious about your
acceleration in the period before reaching your max speed. That part of your course being
approximately one-half of the length of your marked course.
