Question

Calculate the maximum speed with which a car can be driven safely
along a curved road of radius 30 m and banked at 30° with the
horizontal. Given, g = 9.8 ms 2.
1) 13.03 ms 2) 12.08 ms -1 3) 15.08 ms-1 4) 14.02 ms -1​

Answer 1

Explanation:

4" (and any subsequent words) was ignored because we limit queries to 32 words.

Answer 2

• Given :

Radius = 30 m

Angle = 30 degree

g = 9.8 m/s^2

• To Find :

Vm = ?

• Formula :

$v = \sqrt{rg \: \tan(30) }$

• Calculation:

$v = \sqrt{30 \times 9.8 \times \frac{1}{ \sqrt{3} } }$

$v = 13 \frac{m}{s}$
