1. Warm Up

2. Two blocks of mass m = 2 kg and M = 5 kg are hanging off a single pulley, as shown. Determine the acceleration of the blocks. Ignore the mass of the pulley

3. Physics Honors C –Day 11/16-11/17 Centripetal Force

4. Circular Motion

5. What is circular motion? a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation. there must be an inward force acting upon it in order to cause its inward acceleration

6. The tangential velocity t

7. Centripetal acceleration

8. Centripetal Force

9. So what keeps the water in the bucket? What keeps these kids on the wall? Inertia

10. Centripital Force with Gravity

11. Example Problem A 2 kg rock tied to a string is traveling at a constant speed of 4 m/ s in a circular radius of 1.5 m. Calculate the Tension in the string. What is the direction of the centripetal force?

12. Example Problem A 1500 kg car is rounding a curve with a radius of 30 m. If the coefficient of static friction between rubber and the wet road is 0.7, what is the fastest velocity the car can drive and safely make the turn?
