question 58

Multiple Choice

The displacement of an object oscillating on a spring is given by x(t) = x_mcos(+ ) .If the initial displacement is zero and the initial velocity is in the negative x direction, then the phase constant 11ef007a_3990_6877_bc85_811eff4e9b0d_TB6585_11 is:

• A)"0 radians"
• B)"\(\pi\)/2 radians"
• C)"\(\pi\) radians"
• D)"3\(\pi\)/2 radians"
• E)"2\(\pi\) radians"
