The equation of motion of a particle undergoing simple harmonic motion in the y direction is y = (2.0 cm) sin(0.60 s-1 t). At time t = 0.60 s determine the particle's (a) position, (b) velocity, and (c) acceleration.
Experimental Studies
Research methods that involve the manipulation of variables to determine cause-and-effect relationships.
Variables
