Abug flying horizontally at 0.65 m/s collides and sticks to the end of a uniform stick hanging vertically. after the impact, the stick swings out to a maximum angle of 5o from the vertical before rotating back. if the mass of the stick is 10 times that of the bug, calculate the length of the stick. round your answer to the nearest whole centimeter.

The angular momentum is defined as,

Acording to this text we know for conservation of angular momentum that

Where is initial momentum

is the final momentum

How there is a difference between the stick mass and the bug mass, we define that

Mass of the bug= m

Mass of the stick=10m

At the point 0 we have that,

Where l is the lenght of the stick which is also the perpendicular distance of the bug's velocity

vector from the point of reference (O), and ve is the velocity

At the end with the collition we have

Substituting

Applying conservative energy equation we have

Replacing the values and solving

Substituting

l=\frac{13}{0.54(9.8)}

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
