Physics 1 Question?

Question

Hey! Please any help on this problem! I am really stuck on this one. Any help would be great.

An object moves uniformlly around a circular path of radius 16.0 cm, making one complete revolution every 1.65 s.

a) What is the translational speed of the object? (answer is in m/s)

b) What is the frequency of motion in hertz?
I already got the answer to this, .606 Hz

c) What is the angular speed of the object? (answer is in rad/s)

Answer 1

The circumference of the track is 2*pi*.16 m

The object makes the journey every 1.65s,
therefore it's translational speed is:
2*pi*0.16/1.65 m/s

c Radians per second is:
2*pi/1.65 Radians per second
