Question

A toy car moves around a circular track at constant speed. It suddenly doubles its speed - a change of a factor of 2. As a result, the centripetal acceleration changes by a factor of No change since the radius doesn't change. 1/4. 2. 1/2. 0 4.

Answer 1

4

Step-by-step explanation:

because

`centripital \: force = \frac{m {v}^(2) }{ r} \\ if \: velocty \: will \: be \: double\\ so \: \\ force \: will \: be \:4 \: times`
