    Pendulum Period
AI Thread Summary
Pendulum A, with a length of 20 cm and a 5g mass, has a period of 0.20 seconds, while Pendulum B, with a length of 30 cm and a 10g mass, has a period of 0.25 seconds. The mass of the pendulum does not affect the period, which is determined by the length of the pendulum. The correct formula for the period of a simple pendulum is needed for accurate calculations. It is suggested to look up the formula rather than derive it from complex equations. Understanding the relationship between length and period is crucial for solving pendulum problems effectively.

Homework Statement


Pendulum A is 20 cm long and has a 5g mass on it. Pendulum B is 30 cm long and has 10g mass on it. Which one has a faster period?


Homework Equations



d=v1t+0.5at^2

The Attempt at a Solution



First of all, does the mass of the pendulum matter at all? and if not then it I would need to find the time in both cases and divide by 1 right?

Time Pendulum A= 0.20 s which means that the period is 0.20 s.
Time Pendulum B= 0.25 s which means that the period is o.25 s.

Am I right? Thank you in advance.

?

Time Pendulum A= 0.20 s which means that the period is 0.20 s.
Time Pendulum B= 0.25 s which means that the period is o.25 s.
Whence these numbers?

No.
What's the formula for the period of a simple pendulum?
 
I do not know because we have not learned it. >.<

Then you'll have to derive it from the differential equation relating restoring torque to angular acceleration for small deviational angles.

Really it would be simpler for you to just look it up though.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
