Question

A particle is moving along a circular path of radius 5 m with a uniform speed of 5 m/s. What will be the
average acceleration when the particle completes half revolution?
(A) Zero
(B) 10 m/s
(C) 10nm/s
(D) 10/7 m/s​

Answer 1

Answer:

I think option C is right answer...

Answer 2

Answer:

Explanation:

Average acceleration = net velocity / time period

Net velocity = 5 - (-5) <direction of both  components are at 180⁰ >

                       = 10m/s

Time period for half revolution  = π r / v

                                                     = π  5/5 = π

                                                Av acc =  10 /π

pls check your question as this is the correct ans

                   Hope  u understand
