Zog and Geraldine (his wife) each push a cart along a horizontal surface where friction is negligible. Both carts are initially at rest. Zog takes the cart with mass 25kg and exerts a force of 400N on it force for a period of 4.0 s and he then collapses and stops pushing. Geraldine has to push a cart of mass 50 kg and she is also able to exert a force of 400N on it. Geraldine claims that it is impossible for the speed of her cart to eventually reach the speed of Zog's cart. Is this true? Describe
