1: Solve for acceleration. Write the units of your answer next to the number What is the acceleration of a drag racing car that accelerates from 0 to 32 m/s in 4.5
seconds?
2) A sky diver jumps out of a plane. If the diver falls from rest (0 m/s) and reaches a speed
of 18 m/s in 1.92 seconds, what is the diver's acceleration ?

May someone explain how to do this question?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Imagine you are standing in the antarctic during the southern hemisphere summer. the sky is clear and blue. there are no clouds in the sky. your shadow is cast on the icy ground. what is the color of the shadow?
