Answer:
2. 3.1415 m/s
3. 0.63m
4. 0.006 m/s^2
Step-by-step explanation:
2. v=(2*pi*r))/T, put in values and solve.
3. Circumference=2*pi*radius, radius is 0.1m, plug in and solve.
4. a=(v^2)/r, (don't worry about converting to meters, since units are the same in kilometers, they will cancel out) plug in values and solve.
That's it!
