A transverse wave on a string is described by the displacement function D (:13, t) = (0.1m) sin (27m: -l- 67rt) where a: is in metres and t is in seconds. (a) What is the transverse velocity of the segment at :1: : 2.2m at t 2 2.05? Depending on your numbers, the answer may be positive or negative. (b) What is the transverse acceleration of the segment at m : 2.2m at t : 2.05? Depending on your numbers, the answer may be positive or negative, m/s2
