Question

A truck is traveling with a constant speed of 15 m/s. When the truck follows a curve in the road, its centripetal acceleration is 4.0 m/s2. What is the radius of the curve

Answer 1

The radius of the curve is 56.25 m

Step-by-step explanation:

Given

Speed, v = 15 m/s

Centripetal acceleration, a = 4 m/s²

Radius of the curve, r = ?

We know,

r =
`(v^(2) )/(a)`

r =
`(15^(2) )/(4)`

r =
`(225)/(4)`

r = 56.25 m

Therefore, the radius of the curve is 56.25 m
