A 2 N neuton force is applied to a a2.5 Kg dry ice puck that moves frictionlessly across a desktop. If the puck starts at rest, how fast will it be moving after the force is applied? If the puck were moving at 0.6 m/x, how long would it take to bring the puck to a stop?

  • physics -

    ma=F => a=F/m=2/2.5=0.8 m/s²
    v=v₀-at
    v=0
    t=v₀/a=0.6/0.8=0.75 s.
