16.  Two skaters, a man and a woman, are standing on ice. Neglect any friction between the skate blades and the ice. The mass of the man is 82 kg, and the mass of the woman is 48 kg. The woman pushes on the man with a force of 45 N due east. Determine the acceleration (magnitude and direction) of (a) the man and (b) the woman.

 

Draw free body diagram of woman and man.

Now write out sum of the forces equations for each

 

Woman

Man

 

 

 

 

 

To find acceleration of man use the x component equation

 

 

 

Similarly for the woman
