Given:

The radius of the circular exit ramp   =  30 meters

Mass of the car = 2000 kg

Time  = 10 seconds

To Find :

The Speed of the car = ?

Solution:

We know that speed  =  ---------------(1)

Here the distance is the circumference of the circular exit ramp

Then circumference  =

where r is the radius

On substituting the values

Distance =

Distance  = 188.5 meters------------------------(2)

Substituting (2) in (1)

speed = seconds

Speed = 18.85 meters per seconds
