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

Respuesta :

The radius of the curve is 56.25 m

Explanation:

Given

Speed, v = 15 m/s

Centripetal acceleration, a = 4 m/s²

Radius of the curve, r = ?

We know,

r = [tex]\frac{v^{2} }{a}[/tex]

r = [tex]\frac{15^{2} }{4}[/tex]

r = [tex]\frac{225}{4}[/tex]

r = 56.25 m

Therefore, the radius of the curve is 56.25 m
