Homework Help: A quick distance/time question.

  1. Jan 11, 2013 #1
    1. The problem statement, all variables and given/known data
    A radar pulse projected at an angle of elevation of 22.0 degrees is reflected from an aircraft and returned. If the pulse takes 1.28*10^-4s to make the round trip, then the vertical height of the aircraft is? (Height of radar transmitter/receiver can be ignored)

    2. Relevant equations

    3. The attempt at a solution

    I know how to do it, just use d=vt to find the hyp and then use sin feta to find vertical height.

    But for time do i use 1.28*10^-4s? or use half of that since that time is the round trip?

    I woud do it that way, you have the right thinking... you can also use that time and get the total distance and devide that by 2...

    I thought feta was a type of Greek cheese.
