AP Physics 1· difficulty 1/5

A drone flies in a straight line at a constant 20 m/s20~\text{m/s} for 12 s12~\text{s}. What is its displacement?

  • A

    180 m180~\text{m}

  • B

    120 m120~\text{m}

  • C

    320 m320~\text{m}

  • D

Explanation

At constant velocity, Δx=v Δt=(20)(12)=240 m\Delta x = v\,\Delta t = (20)(12) = 240~\text{m}.
