Question

An object is experiencing an acceleration of 12 m/s2 while traveling in a circle of radius 5.0 m. What is its velocity?

Answer 1

Answer:

v = 7.74 m/s

Explanation:

Given that,

The acceleration of the object, a = 12 m/s²

The radius of the circle, r = 5 m

We need to find the velocity of the object. The centripetal acceleration act on the object that is given by :

$a=\dfrac{v^2}{r}\\\\v=\sqrt{ar} \\\\v=\sqrt{12\times 5} \\\\v=7.74\ m/s$

So, the velocity of the car is 7.74 m/s.
