A body on the circular orbit makes an angular displacement given by ∅(t)=2t^2+5t+5. If time t is in seconds, calculate the angular velocity at t=2s

Respuesta :

Answer:

Angular Velocity at 2 s= 13 rad/s

Explanation:

∅(t)=2[tex]t^{2}[/tex] + 5t + 5

where represents angular displacement at any given time t

Angular Velocity (ω)= [tex]\frac{\textrm{d ∅(t) }}{\textrm{dt}}[/tex]

ω=4t+ 5

Putting in t=2

ω=8+5=13 rad/s
