With x - x0 = h and a = g, Equation 2.11 gives the speed of an object thrown downward
Chapter 7, Problem 41(choose chapter or problem)
With x - x0 = h and a = g, Equation 2.11 gives the speed of an object thrown downward with initial speed v0 after its dropped a distance h: v = 2v2 0 + 2gh. Use conservation of mechanical energy to derive the same result.
