Can someone please help me with this problem, a hint, anything something????(adsbygoogle = window.adsbygoogle || []).push({});

A girl throws a stick with a length of 0:25 m

and a mass of 0.53 kg into the air in such a

way that the center of mass rises vertically.

At the moment it leaves her hand, the stick

is horizontal and the speed of the end of the

stick nearest to her is zero. When the center

of mass of the stick reaches its highest point,

the stick is horizontal, and it has made 33

complete revolutions. Assume that the stick's

cross sectional area and mass is uniform.

The acceleration of gravity is 9.8 m/s^2 (speed of stick end

is zero when it leaves her hand)

How long did it take for the center of mass

to reach its highest point? Answer in units of

s.
