My sister Crystal of mass M1= 50 kg is on an ice-covered sidewalk with her dog Buster, who has mass M2= 38 kg. They are initially a distanced= 5.0 m apart.By pulling on the massless leash, my sister exerts a constant force F= 30.0 N on Buster; Buster slides towards her. How fast is Buster moving when he and my sister meet? (The leash is not rigid, so the distance can change between them. They also end up at the same point, which means even if you can’t solve for their position,you can set them equal to one another.)
