A certain escalator travels at a rate of 10.6 m/min, and its angle of inclination is 32.5 degrees. What is the vertical component of the velocity? How long will it take a passenger to travel 10.0 m vertically?

  • Algebra II -

    v = 10.6
    vx = 10.6 cos 32.5
    vy = 10.6 sin 32.5

    Now that you have vy, the time to travel 10m is just
    t = 10/vy
