Question

11. What is the angular displacement made by a particle after 5s,
When it starts from rest with an angular acceleration 0.2 rad s??
a) 4 rad b) 1 rad c) 2.5 rad d) 5 rad
n
i m an arhit around the earth the ratio of kinetic​

Answer 1

Answer: 2.5 radians

Explanation: you solve this by applying the angular variant of the equation of motion.

S = it + {(at^2)/2}

Replace displacement by angular displacement acceleration by angular acceleration and put the values you will get the answer.
