Problem 2-98 - Linear Kinematics - (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.
The time of flight of the signal is:
(A) \(3.4\; s\)
(B) \(3.4\; s \; +\) the time during which the helicopter moves.
(C) \(3.4\; s\; -\) the time during which the helicopter moves.
