Problem $13\mathrm{.}060-$ DEPENDENT MULTI$-$PART PROBLEM $-$ ASSIGN ALL PARTS

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part. A $500-$g collar can slide without friction on the curved rod BC in a horizontal plane. Consider that the undeformed length of the spring is $80$ mm and that $k=400k\frac{N}{m}.$

Problem $13\mathrm{.}060.$a $-$ Collar velocity around curved rod

Determine the velocity that the collar should be given at $A$ to reach $B$ with zero velocity.

The velocity that the collar should be given at $A$ to reach $B$ with zero velocity is $\frac{m}{s}$
