1. 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?

 a. 16.8 kg·m/s b. 15.3 kg·m/s c. 12.9 kg·m/s d. This cannot be answered because the mass of the man needs to be known.

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.
