Firstly, let's convert the velocities in km/hr to m/s
32*1000/3600=8.89m/s
54*1000/3600=15m/s
From the formula, acceleration=V-U/t
15-8.89/8=0.76m/s²
hope this helps.
Explanation:
Acceleration is the change in speed over a given time period
An echo
Refraction
Diffraction
Transmission
reflection
I think it false. Sorry if i'm wrong.
