Calculate the terminal velocity for a baseball. A baseball's diameter is approximately d = 0.073 m, and its mass is m = 0.146 kg. Express your answer in meters per second and miles per hour. (Assume a drag coefficient of 1 and air density of 1.3 kg/m3.)
M g = (1/2) * (density) V^2 * Area * Cd
They tell you to assume the drag coefficient (Cd) is 1.
Compute the baseball's area and solve the above equation for V.
Then convert m/s to miles per hour.
We will be glad to critique your work
