A grenade of mass 0.60 kg is at rest on a frictionless surface when it explodes into 3 pieces.
The first piece has a velocity of 4.0 m/s [E] and a mass of 0.25 kg. The second piece has a
velocity of 7.5 m/s [W 30.0° S] and a mass of 0.10 kg. Find the mass and velocity of the third
piece.

Show Calculation. Thank You :)

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
