Passage Question

A Particle Moves On A Cirular Path Of Radius 7m With Constant Speed 7ms-1

Question No.1: The Magnitude Of Average Velocity During Revolution Through Quarter Circle


Question No.2: The Magnitude Od Acceralation Of The Particle Is?

Question No.3: The Magnitude Average Acceralation in m/s2
during travelling quarter cycle?​

Answer 1

Answer:

10m/s2.

Explanation:

When the particle completes half revolution change in velocity

Δv=[5−(−5)]m/s=10m/s

Time taken to complete the half revolution is

t=vπr=5π×5=πs

Thus, average acceleration =tΔv=π10m/s2.
