Problem 2-98 - Linear Kinematics - Part 4 - (c)
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.
Accumulated Solution
\(d = vt \\ d = (350\; m/s)(3.4\; s) = 1190\; m\)
No. There are no averages involved here. This is just a case of relative motion at constant speed.
