A transverse wave on a string is described by the displacement function D (1, + ) = (0.3 m ) sin ( 1 Te + 2 at ) Where I is in metres and t is in

I am not sure how to use the displacement function to find transverse velocity and transverse acceleration.

A transverse wave on a string is described by the displacement functionD (1, + ) = (0.3 m ) sin ( 1 Te + 2 at )Where I is in metres and t is in seconds .It an answer is Very small le.q. I . 10~ ~ or smaller) . this answer should be rounded to U.(a) What is the transverse Velocity of the segment at I - U.S matt = 5 {?`; What is the transverse acceleration of the segment at I = 1.5 matt = 5 571 1 . 8:4
