An object starts to rotate about an axis from rest wih a, uniform angular acceleration of 2pi rads-2 what is the no. of rotations it can complete in 5s

θ = 12.5 rotations

Explanation:

The number of rotations can be found by using the second equation of motion:

where,

= angular displacement = ?

ωi = initial angular speed = 0 rad/s

t = time = 5 s

α = angular acceleration = 2π rad/s²

Therefore,

converting it to no. or rotations:

θ = 12.5 rotations

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
