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?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
