Question
Find the maximum speed at which car turns round a curve of 30 m radius on a level road if the coefficient of friction between the tyres and the road is 0.4.
Solution
The maximum speed of car is given by,
Here,
Limiting friction, 
Radius of the track, r = 30 m
Acceleration due to gravity, 
∴
Maximum speed, ![<pre>uncaught exception: <b>mkdir(): Permission denied (errno: 2) in /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php at line #56mkdir(): Permission denied</b><br /><br />in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php line 56<br />#0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array)
