What's the centripetal acceleration of an object traveling 2.3 m/s around a circle of diameter 0.6 m?

• 5 m/s²

• 17.63 m/s²

• 10 m/s²

• 8.81 m/s²

A compact disk is rotating at 220 rpm, this is equal to:

• 1382.30 rad/s

• 23.03 rad/s

• 82938.04 rad/s

• 220 rad/s

The unit used for frequency is...

• m/s

• m/s²

• hertz

• seconds

I a windmill_(r=5 m) receives an angular acceleration of

 $3\ \frac{rad}{s^2}$  , the tangential acceleration will be equal to:

•  $15\ \frac{m}{s^{2\ }}$  

•  $0.6\ \frac{m}{s^2}$  

•  $1.66\ \frac{m}{s^2}$  

•  $30\ \frac{m}{s^2}$
