ADDITIONAL PROBLEMS Question 13.1a A 0.495-kg block attached to a spring is observed to oscillate in simple harmonic motion with a velocity given by v = -(3.25 m/s)sin(7.75 t). (a) Determine the angular frequency w, amplitude A, and period 7 of the block's motion. w = 7.75 A = 0.419 T = 0.81 rad/s m S (b) Determine the position of the block at t = 1.70 s. (Include the sign of the value in your answer.) -0.38 Xm (c) Determine the spring constant k. 29.7 N/m
