An inclined railway travels at a speed of 1.10 m/s while climbing at an angle of 35.0°. The railway delivers riders to the top of a mountain – a change in elevation of 125 m. (a) Determine the rate at which the train’s elevation increases. (b) Determine the time for it to reach the top.

Aforce of 9.00 newtons acts at an angle of 19.0 to the horizontal. what is its component in the horizontal direction?

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.

More solar radiation is absorbed by earth’s surface than by
