The angular motion of a disc is defined by the relation (θ = 3t + t3), where θ is in radians and t is in seconds. What will be the angular position after 2 seconds?
  • a)
    14 rad
  • b)
    12 rad
  • c)
    18 rad
  • d)
    16 rad
Correct answer is option 'A'. Can you explain this answer?

Angular motion θ = 3t + t3
Motion covered in 2 seconds = 3 * 2 + 2= 14 rad. So the angular position after 2 seconds will be 14 rad.

Theta(t) = ωt + 0.5αt^2,

where theta(t) is the angular position of the disc at time t, ω is the angular velocity of the disc, and α is the angular acceleration of the disc. This equation describes the motion of the disc as it rotates about its axis.
