Work this exercise by the two given procedures as directed, commenting on and explaining any difference in the answers. Use your calculator for the calculations. Compute ρ = mv, where v = x/t, given x = 8.5 m, t = 2.7s, and m = 0.66kg.
(a) First compute v and then p.
(b) Compute ρ = mx/t without an intermediate step.
(c) Are the results the same? If not, why?
