A curved road is $7.5 m$ wide and its outer edge is raised by $1.5 m$ over the inner edge. The radius of curvature is $50 m$ . For what speed of the car is this road suited? $(g = 10 m / s^{2})$ :
$5 m / s$
$10 m / s$
$15 m / s$
$20 m / s$

$N s i n θ = \frac{m v^{2}}{R}$

$N c o s θ = m g$

$t a n θ = \frac{v^{2}}{r g}$

$t a n θ = \frac{1.5}{7.5}$

$\frac{1}{5} = \frac{v^{2}}{50 \times 10}$
