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 acceleration 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 acceleration will her groceries have?

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?
