Exercise 112

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 p = mv , where v = x/t , given x = 8.5 m, t = 2.7 s, and m = 0.66 kg. (a) First compute v and then p. (b) Compute p = mx/t without an intermediate step. (c) Are the results the same If not, why
