Questions
A particle is moving along a circular path of radius 5 m and with uniform speed 5 m/s. What will be the average acceleration when the particle completes half revolution
detailed solution
Correct option is D
The change in velocity when the particle completes half revolution is given byΔV=5m/s−(−5m/s)=10m/sTime taken to complete half revolutiont=πrv=π×55=π∴ Average acceleration =Δvt=10πm/ss=10πm/s2Talk to our academic expert!
