Finding Final Velocity
Use the formula $\nu=\mathrm{r} \omega$ to find the value of the missing variable. $r=25 m, \omega=\frac{4 \pi}{5}$ radians per sec
The missing variable is $\nu=$ $\mathrm{m}$ per sec.

Finding Average Acceleration
Question 23
1 pts
You travel in circle of radius $5 \mathrm{~m}$. Initially, you are moving at a speed of $5 \mathrm{~m} / \mathrm{s}$ in what we will take to be the positive direction. 2 seconds later, you are at the diametrically opposite point on the circle, again moving at $5 \mathrm{~m} / \mathrm{s}$. What is your average acceleration over this time interval? $\mathrm{m} / \mathrm{s}^{2}$

1. A crazy dog runs 300 meters east, changes his mind and then runs 200 meters west. He then changes his mind again and runs 500 meterg east. This entire trip takes 2 minutes.
a) What is the total distance traveled?
b) What is the total displacement?
c) What was the dog's average speed?
d) What was the dog's average velooity?
2. A. long distance running is running the $10000 \mathrm{~m}$ race. He runs the first $2000 \mathrm{~m}$ in 5 minutes, the next $5000 \mathrm{~m}$ in 14 minutes and the final 3000 meters in 7 minutes. What was the runnar's
