Given : For a particle’s journey, the magnitude of average velocity is 20 m/s
To Find : Which among the following cannot be the value of average speed?
Solution:
Average Velocity = Total Displacement / Total Time
=> 20 = Total Displacement / T
=> Total Displacement = 20T
Average Speed = Total Distance / Total Time
Displacement is the minimum Distance
Hence Displacement ≤ Distance
=> 20T ≤ Distance
Hence Average Speed ≥ 20T / T
=> Average Speed ≥ 20 m/s
Hence 15 m/s can not be the value of average speed
