The 68-kg crate is stationary when the force p is applied. determine the resulting acceleration of the crate if (a) p = 0, (b) p = 181 n, and (c) p = 352 n. the acceleration is positive if up the slope, negative if down the slope.

The equation that describes a transverse wave on a string is y = (0.0120 m)sin[(927 rad/s)t - (3.00 rad/m)x] where y is the displacement of a string particle and x is the position of the particle on the string. the wave is traveling in the +x direction. what is the speed v of the wave?
