What distance will a sliding hockey puck with a kinetic energy of 500j go if it is experiencing a normal force of 20n on ice with a friction constant of 0.1??

Describe the path of a ray that approaches a mirror parallel to the principal axis.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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.
