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?

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.
