To solve this problem we will apply the concept related to the amplitude and the Doppler effect. The difference between the maximum and minimum frequency detected by the microphone would be given by the mathematical function
Here,
= Source Frequency
= Speed of microphone
v = Speed sound
Maximum speed of the microphone is
Now the amplitude is
Here T means the Period, then
A= 0.2605m
Therefore the amplitude of the simple harmonic motion is 0.2605m
Hi there,
Unlike velocity,speed is scalar,which means it is described by MAGNITUDE only.

The forces are equal because of Force = mass x acceleration. The launcher has a greater mass therefore the acceleration is less. The ball has a greater acceleration and less mass, the ball is faster. ( m delta t) Impulse = mass x velocity = momentum (m delta v) assuming the launcher has more mass, the ball has more momentum.
