Circular Motion Barbie is whirled in a horizontal circle on a 1.0 meter long string, such that the string makes a 10.° angle with the horizontal. Calculate Barbie's tangential speed

Please explain how to do it

30 degrees to the right

Explanation:

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.

the answer is 3.1 his answer is wrong mines is right
