AI Thread Summary
To calculate the length of a pendulum with a period of 0.75 seconds, the length is determined to be approximately 0.142 meters. The speed of the pendulum at the bottom of its swing, given a maximum displacement angle of 11 degrees, is calculated using energy conservation principles. The height difference between the highest and lowest positions is crucial for this calculation. The final speed is determined to be approximately 0.23 m/s. This discussion highlights the importance of understanding pendulum dynamics and energy conservation in physics.

Please Help!

ok could someone plesae help me with this question

I had to draw a pendulum and the questions asks what is the length of the pendulum if the period is .75 s so i got .142 m then it asks what is the speed of the pendulum at the bottom of its swing if the angle that makes its maximum displacement is 11 degrees? wow do i do that... I have no idea?


PLEASE HELP!

c'mon 11 views no help I am sure someone out there knows it
 
HINT 1: What is the difference in height between the highest and lowest positions of the pendulum.

HINT 2: Energy is conserved. :)
 
difference is .142m - .03m i don't see how it helps
 
is teh answer by any chance .16 or .23
 
What are the units of speed? And how did you get those numbers?
 
.23 m/s

(2pi/T)A
(spi/.75)(.142sin11)= .23m/s
