A string of linear density 1.60 g/m is stretched between
Chapter 18, Problem 81(choose chapter or problem)
A string of linear density 1.60 g/m is stretched between clamps 48.0 cm apart. The string does not stretch appreciably as the tension in it is steadily raised from 15.0 N at t 5 0 to 25.0 N at t 5 3.50 s. Therefore, the tension as a function of time is given by the expression T 5 15.0 1 10.0t/3.50, where T is in newtons and t is in seconds. The string is vibrating in its fundamental mode throughout this process. Find the number of oscillations it completes during the 3.50-s interval.
