A car of mass...

Question

A car of mass $2000$ kg rounds a curve of radius $250$ m at $90$ km/hr. Compute its Angular speed.

Open in App

Solution

$v e l o c t i y = R a d i u s \times A n g u l a r V e l o c i t y$
$v e l o c i t y = 90 \times \frac{5}{18} m / s$
$v e l o c i t y = 25 m / s$
$a n g u l a r v e l o c i t y = \frac{v e l o c i t y}{r a d i u s} = \frac{25}{250} = 0.1 r a d / s$
