Period of a Pendulum
- determined by ....
Length
T = 1/f
Finding the height of a
pendulum
KE1 + PE1 = KE2 + PE2
Ex) A pendulum is pulled back at an angle of 10 degrees from the vertical and is released. When the ball reaches the lowest point, it has a velocity of 2 m/s.
What is the frequency of the pendulum?
KE1 + PE1 = KE2 + PE2
mgh = = 1/2mv2
mg(L - Lcosq) = 1/2mv2
L = 13.2 m
T = 7.2 sec
T = 1/f
T = .14 Hz
