1 The equation of a transverse wave on a string is ? = (2.0 ?)sin(20? − 600?). What is the wave speed of the wave and the lineardensity of the string if it has a tension of 15 ??
2 A block is in simple harmonic motion on the end of a springwith its position given by ?(?) = ? cos(?? + ?). If ? = ?/5 ???,then at ? = 0 ? what percentage of the total mechanical energy ispotential energy?
