Question

A particle is moving along a circular path of radius 5 m, moving with a uniform speed of 5ms−1. What will be the acceleration​

Answer 1

Answer:

$\huge\color{pink}\boxed{\colorbox{Black}{❥ Answer}}$

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

Answer 2

$\huge\color{pink}\boxed{\colorbox{Black}{❥ Answer}}$

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
