Circular motion

The mass point regularly moves in a circle with radius r = $r m angular velocity ω = 4.3 rad/s. Calculate the period, frequency, and centripetal acceleration of this movement.

Correct answer:

T =  1.46 s
f =  0.68 Hz
a =  20.34 m/s2

Step-by-step explanation:

r=1.1 m ω=4.3 rad/s  ω = 2 π f f = 1/T  ω = 2 π / T  T=ω2π=4.32 3.1416=1.46 s
f=T1=1.46121=0.68 Hz
a=r ω2=1.1 4.32=20.34 m/s2
