5 While traveling on a curved dusty road, a car gets a centripetal acceleration of 12.5 m/s2. If the radius is 1200 m, what is the tangential velocity of the car? 6. Find the mass of a circular moving object that has a centripetal force of 1345 N and an accel-eration of 36.2 m/s2.

7. Ruichao is spinning her backpack around and around. If her backpack has a mass of 8 kg, what centripetal acceleration would it have if she applies a centripetal force of 120 N?

8. Callum is playing tetherball. The tetherball has a mass of 0.4 kg and has a tangential velocity of 2.4 m/s. If the tetherball rope is 1.5 m long, what centripetal force does Callum’s tetherball have?

9. Melissa and Cody are on a fun fair ride that spins them in a circle with radius 6 meters. If Melissa has a mass of 55 kg and Cody has a mass of 65 kg, what centripetal force will they have together if they have an acceleration of 2.2 m/s2?

10. Bethany is swinging her grocery bag as she walks. The radius of her swing is 0.8 m. If she can provide a tangential velocity of 2.7 m/s and a centripetal force of 68 N, what centripetal accel-eration will her groceries have?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
