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?

(I'm sorry I need help with those problems)
