Unformatted text preview: seek the velocity v p at x = 13 m. If we obtain a real, nonzero answer, then our suspicion is correct (that it does reach this point P at x = 13 m). By energy conservation, the mechanical energy at x = 7.0 m is equal to the mechanical energy at P . Therefore, 75 J = 1 2 mv p 2 + 1 2 I com p 2 + U p Again, using item ( f ) of Table 112, Eq. 112 (less trivially this time) and U p = 60 J (from the graph), as well as the numerical data given in the problem, we find v p = 7.3 m/s....
