We are given that,
We need to find 
when 
The equation that relates x and 
can be written as,
Differentiating each side with respect to t, we get,
Replacing the value of the velocity
The value of 
could be found if we know the length of the beam. With this value the equation can be approximated to the relationship between the sides of the triangle that is being formed in order to obtain the numerical value. If this relation is known for the value of x = 6ft, the mathematical relation is obtained. I will add a numerical example (although the answer would end in the previous point) If the length of the beam was 10, then we would have to

Well, one of the theories was that Charles darwin proved that theory evolution is real so that one theory.
A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies
