A 20. -kg lead sphere is hanging from a hook by a thin wire3.5m long, and is free to swing in a complete cirle. Suddenly it isstruck horizontally by a 5.-kg steel dart that embeds itself in thelead sphere. What must be the minimum intial speed of the dart, so that the combination makes a complete circular loop afterthe coolision?
