Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points A body oscillates with simple harmonic mo tion along the xaxis. Its displacement varies with time according to the equation x ( t ) = A sin( t + ) . If A = 7 m, = 3 . 313 rad / s, and = 1 . 0472 rad, what is the acceleration of the body at t = 3 s? Note: The argument of the sine function is in radians rather than degrees. Answer in units of m / s 2 . 002 10.0 points A 0 . 325 kg mass is attached to a spring and undergoes simple harmonic motion with a pe riod of 0 . 56 s. The total energy of the system is 4 . 4 J. Find the amplitude of the motion. Answer in units of m. 003 (part 1 of 4) 10.0 points A 0 . 1 kg block attached to a spring of force constant 9 N / m oscillates with an amplitude of 13 cm....
