Circular motion

The mass point regularly moves in a circle with radius r = 3.4 m angular velocity ω = 3.6 rad/s. Calculate the period, frequency, and centripetal acceleration of this movement.

Correct answer:

T =  1.75 s
f =  0.57 Hz
a =  44.06 m/s2

Step-by-step explanation:

ω=2πf f=1/T T=2π3.6=1.75 s
f=1/T=0.57 Hz
a=rω2=3.43.62=44.06 m/s2
