Problem C15: An object of mass m is thrown up vertically into the air with an initial speed v0. It travels to a maximum height h and returns to the ground. The object's speed when it hits the ground is v. During its travel through the air, the force of air friction is constant, and equal to f. If v/v0 = (n1/n2)1/2 what is f? If f=mv02/(hn3), what is n3? Note that n1, n2 and n3 are unitless.

n1 = n2 = Input n3:
