a body starts rotating from rest at the rate of 6 rotations per/ secsquare after 8 secs how many rotations will it complete?
rate of 6 rotations per/ secsquare
--- rate of 6 rotations per/ sec^2 <---- looks like acceleration
so a = 6
v = 6t + c
but it started from rest, so when t = 0 , v = 0, then c = 0
v = 6t , v is the speed of the rotation
and
s = 3t^2 , where s is the number of rotations.
when t = 8
s = 3(64) = 192
