Questions
If an object starts from rest and covers angle of 60 rad in 10s in circular motion, then magnitude of its angular acceleration will be [JIPMER 2019]
detailed solution
Correct option is A
Given, initial angular velocity of object, ω0=0Angular displacement, θ=60radand Δt=10sFrom equation of rotational motion, θ=ω0t+12αt260=0×t+12×α×102⇒ α=6050⇒α=1.2rads−2Talk to our academic expert!
