Problem 2-98 - Linear Kinematics - (b)
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.
No. If the helicopter travels faster than the signal it will hit the cliff before the signal can reflect off it.
