A car of mass $1000 k g$ moves on a circular path with a constant speed of $16 m s^{- 1}$ . It is turned by $90 °$ after travelling $628 m$ on the road. The centripetal force acting on the car is

Options:

Answer:

Solution:

$\frac{2 π r}{4} = 628$

$r = \frac{628 (2)}{3.14} = 400 m$

Centripetal Force, $F = \frac{m v^{2}}{r}$

$F = \frac{1000 {(16)}^{2}}{400}$

$F = 640 N$
