1. U.C.M.M.C.Qs.in1. The angular displacement is given by0 = at2 + bt + c then its angular velocity att = 1 second is ----(a) 2a + b (b) a + b (c) a - b (d) a + b + c..

Answer»

Given,Angular Displacementtheta = at^2 + bt + c

Angular velocity is given byd(theta)/dt = 2at + b

Therefore,For t = 1Angular velocity = 2a*1 + b= 2a + b

(a) is correct option
