I agree with indr12365

..wats wrong in what she said??in case of the boyfriend,the angle @ btw the legs is less for a step of the same distance as compared to annie..and mgsin@ is the force which propels him...so there is less force in forward direction-so he's slower..

n dude sinha0109..when you give a question just type it a little more carefully,will you?...i got confused when you said 'andy'-i thought it might be the boyfriend!!!

Even in the hemispheres-joined-together thing there was some confusion.
