Using the theoretical mass of an egg as 0.060kg calculate the PE, KE, acceleration, velocity, and momentum at the top, middle (5 meters down), and bottom of a 10 meter tall building. Assume no air resistance. Show ALL work. Pro Tip: Gravity is a thing. DO NOT say that the egg goes 0 m/s at the bottom. It does not freeze before hitting the ground.

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
