Consider a ball that is thrown vertically upwards near the surface of the Earth with initial speed v₀. It goes up, then returns back to your hand. Air resistance can be neglected. Come up with three different methods for finding the time that the ball was in the air. Each method should have a different set of "knowns" that you use. even though you might use the same equation for two different methods. Write out the plan for each method, clearly showing what equation(s) would be used for that method. Then solve for the time using each method to make sure that they all agree.

(a)Fully explain the first method you have come up with.

(b)Fully explain the second method you have come up with.

(c)Fully explain the third method you have come up with.

(d)Show work solving for time using each method to demonstrate that they all agree.
