a 65 kg male skater pushes a 45 kg female skater causing her to accelerate at a rate of 2.0 ms ^2 at what rate will the male skater accelerate? What is the rate of his acceleration?

  • Physics - ,

    Since they exert equal and opposite forces on each other,
    M1*a1 = -M2*a2
    a2 = -a1*(45/65)
    = -1.38 m/s^2

    Subscript 2 denotes male; 1 denotes female.
    The minus sign means the accelerate in opposite directions.
