A scooterist is approaching a circular turn of radius 80 m. He reduced his speed from 27 kmh -1 at constant rate of 0.5 ms -2 . His vector acceleration on the circular turn is
Text Solution
Verified by ExpertsThe correct answer is:
A
Centripetal acceleration
a r = 
= 
= 0.703 ms -2
Net acceleration, a = 
where a t = tangential acceleration = 0.5 ms -2
∴ ∴ a = 
and
θ θ = tan -1
