One of James Bond's adversaries is standing on a frozen lake. There is no friction between his feet and the ice. He throws his steel-lined hat with a velocity of 24.0 m/s at 36.9° above the horizontal, hoping to hit James. If his mass is 120 kg and that of his hat is 5.90 kg, what is the magnitude of his horizontal recoil velocity?
m/s
