A block on a horizontal spring oscillates with amplitude A=0.10 mA = 0.10\text{ m} and angular frequency ω=8.0 rad/s\omega = 8.0\text{ rad/s}. What is its maximum speed?

  • A

    8.0 m/s8.0\text{ m/s}

  • B

    1.6 m/s1.6\text{ m/s}

  • C

    0.80 m/s0.80\text{ m/s}

  • D

    0.10 m/s0.10\text{ m/s}

Explanation

vmax=Aω=(0.10)(8.0)=0.80 m/sv_{max} = A\omega = (0.10)(8.0) = 0.80\text{ m/s}.
