Select the correct answers.
when you throw a ball upward, its kinetic energy (decreases, increases, or remains the same) and its potential energy (decreases, increases, or remains the same) . when the ball reaches maximum height, its kinetic energy is at a (maximum, or minimum).

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?

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed
