AP Physics 1· difficulty 1/5

A motorcycle accelerates from 5.0 m/s5.0~\text{m/s} at 3.0 m/s23.0~\text{m/s}^2 for 4.0 s4.0~\text{s}. What is its final speed?

  • A

    12 m/s12~\text{m/s}

  • B

    20 m/s20~\text{m/s}

  • C

    32 m/s32~\text{m/s}

  • D

    17 m/s17~\text{m/s}

Explanation

v=v0+at=5.0+(3.0)(4.0)=17 m/sv = v_0 + a t = 5.0 + (3.0)(4.0) = 17~\text{m/s}.
