WebJan 16, 2024 · Solving for Terminal Velocity. Use the terminal velocity formula, v = the square root of ( (2*m*g)/ (ρ*A*C)). Plug the following values into that formula to solve for v, terminal velocity. [1] m = mass of the falling object. g = the acceleration due to gravity. On Earth this is approximately 9.8 meters per second squared. Webα = Δ ω Δ t, where Δ ω is the change in angular velocity and Δ t is the change in time. The units of angular acceleration are (rad/s)/s, or rad/s 2. If ω increases, then α is positive. If ω decreases, then α is negative. Keep in mind that, by convention, counterclockwise is the positive direction and clockwise is the negative direction. tepper healthcare club
