1. If they complete a lap once every 8.0 seconds, what force is required to keep moving in this circular path?
1. 40N
2. 150N
3. 220N
4. 300N
2. If the coefficient of friction between the bicycle tires and the road is 0.90 what is the maximum speed at which they can go around this circular path?
1. 2.2m/s
2. 4.4m/s
3. 6.6m/s
4. 8.8m/s
