Questions
A particle is moving along a circular path of radius 6 m with a uniform speed of 8 m/s. The average acceleration when the particle complete one half of the revolution is
detailed solution
Correct option is C
t=π×68 sec = 3π4 sec.After half revolution velocity is reversed.∴ aavg. = Δv→t=8−−83π/4=643π m/s2Talk to our academic expert!
