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 22.6m/sat an angle 37.0 degreesabove the horizontal, hoping to hit James.
If his mass is 113kgand that of his hat is 4.00kg, what is the magnitude of his horizontal recoil velocity?
