Problem 2-98 - Linear Kinematics - Part 2 - (a)
A helicopter is traveling horizontally, straight toward a cliff. When \(700\; m\) from the cliff, it sends a sonar signal and \(3.4\; s\) later receives the reflected signal. Assuming the signal travels at \(350 \;m/s\), determine the speed of the helicopter.
In this time the signal travels a distance \(d\), given by:
(A) \(d = vt\)
(B) \(d = v/t\)
(C) \(d = t/v\)
