A man standing on frictionless ice throws a 1.00-kg mass at 20.0 m/s at an angle of elevation of 40.0°. What was the magnitude of the man’s momentum immediately after throwing the mass?

Thank you for the opportunity to help you with your question!

Horizontal component of throw V = (cos 40) x 20, = 15.32m/sec.
Vertical component has no affect on the problem, because of lack of friction.
His momentum will be the momentum given the mass, which is 15.32kg/m/sec. (1kg x 15.32m/sec.).
Momentum is conserved.

Please let me know if you need any clarification. I'm always happy to answer your questions.
