banked at an angle of 15 degree. With what
speed a car has to move on the turn so that
it will have safe turn?​

Answer 1

Answer:

hope....it...helps......

Answer 2

Answer:

The speed for the car to have a safe turn is 7.1m/s.

Explanation:

Given

Radius of the circular road= 20m

Banking angle of the road = 15 degree

Objective - To find the speed of the speed to have a safe turn.

Step 1

The formula for minimum speed for a vehicle over a banked road is given as

$v=\sqrt{rgtan\theta$

Step 2

Putting given values to obtain the value of v

$v=\sqrt{20(9.8)(tan15)}$

$v=7.1ms^{-1}$

The speed for the car to have a safe turn is 7.1m/s.
