Answer 1

Answer #1

T = 2pi*sqrt(L/g)

squaring on both sides,

T^2 = 4pi^2*(L/g)

L = g x T^2 / 4pi^2

L = 9.81 m/s^2 x 2^2 / (4 x pi^2)

L = 0.9940 m

The period of a pendulum (i.e. the time it takes to swing back and forth over one cycle of motion) can credibly be believed to depend on both the length of the pendulum and the acceleration due to gravity. We can write this as Where C is some unknown constant, L is the length of the pendulum, g is the acceleratio lue to gravity, and x and y are unknown. Using dimensional analysis, determine how T lepends on L and...

A tetherball (aka conical pendulum, like the one we showed in class!) is attached to a string and is rotating around in a horizontal circle. The length of the string is 2.000 meters (which is not 2 the radius!!) and it takes 0.8000 seconds for the ball to go around once. Use g = 9.807 m/s . What angle does the string make relative to vertical? Write your answer to 4 sig figs.

You want to build a pendulum clock in which the time interval during which the "tick" sound is made (pendulum swinging one way) and the time interval during which the "tock" sound is made (pendulum swinging the other way) are each 0.50 s. a) If we assume the pendulum is a simple one, what should its length be?
