Explanation:
An echo may be defined as a sound which is repeated because of the sound waves that are produced are reflected back after striking a surface. Sound waves can smoothly bounce off the hard objects in the same manner as a rubber ball bounces back the ground.

3F = maa = 3F / m
The acceleration is also tripled since the force is directly proportional to the acceleration.
