A car moves on a circular road, describing equal angles about the centre in equal intervals of times. Which of the statements about the velocity of car is true?

Open in App

Solution

the angular speed $ω = \frac{d q}{d t} = \frac{v}{r} = 2 π \times f = c o n s t a n t$
the angular accelaration $\frac{d^{2} q}{d t^{2}} = 0$
the inward acceleration $a = \frac{v^{2}}{r} = ω \times v = c o n s t a n t$
