    Finding Altitude

    Little stumped on a problem here. Plane leaves runway climbing at 15 degrees with constant speed 250 feet per second. Find altitude after 1 minute.

    What would the setup be?? (Not even sure I'm using the right identity)
    sin 15 degrees = X/(250 ft/sec x60 seconds)

    X = 3882.29 ft??? Not sure it's right.
    ------------------
    I simply put 250 ft x 60 s = 15000 ft on my homework, but was wrong.

    Thanks for any help.

    Draw a right angled triangle to visualise the problem...

    250*60=15000

    hypo=15000

    Using sin15=oppo/hypo,

    oppo=15000*sin15

    Oppo=Altitude...
