A car has moved 6.8 m from when the driver saw the red light to come to a full stop. If the driver was moving with 31.7 m/s when they saw the traffic light, how long did it take for them to come to stop?

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?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
