Problem 2-98 - Linear Kinematics - Part 4 - (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.
Accumulated Solution
\(d = vt \\ d = (350 \;m/s)(3.4\; s) = 1190 \;m\)
No. The helicopter is approaching the signal so the distance must be less that \(1190\; m\).
