Question

Suppose s yo ye has a center shaft o,400 cm in rasius and that string is being pulled from it (a) tf the strng is tationary and the yo-yo accelerates aay from it at·rate of 1.50 m/s2, what es its .ngular acceleration? rad/s What is the angular velocity ser 0.750s if it starts from est () The outside radius of the yoyo is 3.50 cm. In the refarence fram of the verye mass center hat is the tangential acceieration of a peint an its edge? nys (Expliutly shove on paper hosw you follow the steps in the Problam-Soving

Explanation / Answer

(a)

= a/r

= 1.5 m/s² / 0.0040m

= 375 rad/s²

(b)

= t

= 375 rad/s² x 0.75s

= 281.25 rad/s

(c)

a = r

a = 375 rad/s² x 0.035m

a = 13.125 m/s²
