while racing on a flat track, a car rounds a curve of 28 m radius and instantaneously experiences a centripetal acceleration of 18 m/s2 . how fast was the car going?

Respuesta :

By 22.4 m/s the car was going.

Given, centripetal acceleration, then apply the following formula.

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

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

a = centripetal acceleration, given = 18

v = velocity

r = radius, given = 28 m

Put these values in formula, [tex]v^{2}[/tex] = a r

v = 22.4 m/s

Therefore, by 22.4 m/s the car was going.
