1. The problem statement, all variables and given/known data Imagine that a bullet is shot vertically into the air with an initial speed of 9800 m/s. If we ignore air friction, how high will it go? vi = 9800 m/s h = ? 2. Relevant equations v2 = vi2 + 2aΔy Ki = Ui --> 1/2mv2 = mgh F = (Gm1m2)/r 3. The attempt at a solution Attempt 1 v2 = vi2 + 2aΔy 0 = (9800 m/s)2 + 2(-9.8 m/s2)(Δy) Δy = 4,900,000 m Attempt 2 1/2mv2 = mgh h = 4,900,000 m Neither of these equations worked, so I tried using gravitational equations, but I couldn't figure it out.
