The wheel of a toy car rotates about an axis on the rough surface. Its angular frequency slows down from $400 rps$ to $200 rps$ in $2 s$ . Then its angular retardation in $r a d s^{- 2}$ is

Options:

Answer:

Solution:

Given, $ω_{1} = 2 π \times (400)$ rad $s^{- 1}$

$ω_{2} = 2 π \times (200)$ rad $s^{- 1}$

$α = 2 π \frac{(400 - 200)}{2} = 200 π radions$ $α$ is the retardation.
