A air-track glider is attached to a spring. The glider is pushed in 10 cm .and released. A student with a stopwatch finds that oscillations take 12.0 s . What is the spring constant?
The spring constant of air track glider is
Mass of the glider is 0.200 g .
No of oscillations is 10 .
Time taken is 12.0 s
The amount of time it takes to complete one cycle, also known as periodic time, is given by
is the angular frequency. k is force constant and m is mass attached with spring.
On your first trip to Planet you happen to take along a mass, a -long spring, a meter stick, and a stopwatch. You’re curious about the free-fall acceleration on Planet , where ordinary tasks seem easier than on earth, but you can’t find this information in your Visitor’s Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by . You then pull the mass down and release it. With the stopwatch you find that oscillations take . Based on this information, what is ?
A penny rides on top of a piston as it undergoes vertical simple
harmonic motion with an amplitude of 4.0cm . If the frequency
is low, the penny rides up and down without difficulty. If the
frequency is steadily increased, there comes a point at which the
penny leaves the surface
a. At what point in the cycle does the penny first lose contact
with the piston?
b. What is the maximum frequency for which the penny just
barely remains in place for the full cycle?
