Question

the angular displacement of a particle is given by tita =t3+t2+t+1 then its angular velocity at t=2s is rad/s​

Answer 1

Answer:

Given that angular displacement of the particle is given by θ=t

3

+t

2

+t+1

So angular velocity = ω=

dt

dθ

=3t

2

+2t+1

= at t = 2 secs

angular velocity =ω=17rads
