Problem 2-98 - Linear Kinematics - Part 2 - (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. Read the question carefully again.

Try again.
