Answer:
When the radius is doubled, its speed will be 42.42 km/h.
Explanation:
Given that,
The maximum speed around a level curve is 30 km/h = 8.34 m/s
We need to find the maximum speed around a curve with twice the radius. The maximum speed of the object is given by :
............(1)
If radius is doubled, r' = 2r
The maximum speed is given by :
..........(2)
Dividing equation (1) and (2) we get :
v' = 42.42 km/h
So, when the radius is doubled, its speed will be 42.42 km/h. Hence, this is the required solution.
