1. The problem statement, all variables and given/known data The figure shows two masses hanging from a steel wire. The mass of the wire is 60.0 g. A wave pulse travels along the wire from point 1 to point 2 in 24.0 ms. What is mass m? 2. Relevant equations v = sqrt(Ts/mu) 3. The attempt at a solution T=mu*v^2 t = 0.024s d = 4m v = d/t = 166.666m/s mu = m/L = 60g/8m = 7.5 T = 208331Nsin40 = mg m = 208331Nsin40/g m = 13.66 but the answer is 17.8kg. where did i go wrong?
