Respuesta :

Answer:

Explanation:

As the 1-meter string is at a 10° angle, the radius of horizontal circle Barbie is whirled will be = 1*cos(10°) meter.

Once the rotation speed is given, then multiple that by cos(10°) will be the tangential speed.

Answer:

Explanation:

cant calculate as no speed is given but the tangential speed is

= rotation speed x radius x cos 10.°

= rotation speed x cos  10.°
