Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.

For calculating the final vertical velocity, is it possible to use the formula: displacement=((initial velocity + final velocity)/2)*change in time? After substituting all the known values in, I get the result −26.017 which is only slightly different from Sal's result.
