Oh okay, so in part a) the r is reffering to 2 Pi Radians or not 2 pi radius?

Would this be suffice to solve it? r = .2m and T = 2s v = 2pi(r) / T a) so just plug in. b) f = 1/T so just plug in again c) omega = v/r so just plug in. On part c) how can I get the final answer to be in rad/sec?

anyone?

Anyone?

I was getting really confused with the algebra, so I just solved for the original length, Lo. Doing this I found it to be .25 meters. After that I used the equation : Delta L = (alpha) (Lo) (delta T), to find the change in length of the aluminum. Delta L = (24 X 10 ^ -6) ( .25) (-25)...

What are you referring to when you say RHSs ?

Frequency = 1 / period correct? So, 1 / 2 sec = .5 rev/sec?

Homework Statement An object moves uniformly around a circular path of radius .20 meters, making one complete revolution every 2.00 sec. What are (a) the translational speed of the object, (b) the frequency of the object, and (C) the angular speed of the object? Homework Equations...

awesome, thanks alot!

So would it be : (2 Pi * sqrt ( l / g)) / 1 sec ?

T = (2pi) *Sqrt (Lo-delta L /9.8) ? How do I find out how much time it loses? Or would it simply be .0006 sec/min

How would you do it algebraically? Would you solve in terms of Lo ?

ok, so : T = (2pi) *Sqrt (.9994/9.8) t = 2.006 s So it loses time?

Homework Statement A 500-g block is released from rest and slides down a frictionless track that begins 2.00 m above the horizontal as shown in the figure. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a constant of 20...

If I assume length = 1 m, then I come up with a Delta L of .0006 m
