Water wave traveling in a straight line on a lake is described by the equation y(x, t)=(2.75cm)cos(0.410rad/cmx+6.20rad /st) where y is the displacement perpendicular to the undisturbed surface of the lake.

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
