# Blue Car and Grey Van Turning

SATPHY-J41Q5F

A blue car rounds a circular turn at a constant speed of $30\, m/s$. A grey van rounds the same turn at a constant speed of $15\, m/s$.

How does the magnitude of the acceleration of the blue car compare to the magnitude of the acceleration of the grey van?

A

The accelerations of both vehicles are zero, since neither is changing speed.

B

The magnitude of the blue car's acceleration is twice the magnitude of the grey van's acceleration.

C

The magnitude of the blue car's acceleration is four times the magnitude of the grey van's acceleration.

D

The magnitude of each car's acceleration is the same, but is not zero.

E

We do not have enough information to determine the relative magnitudes of acceleration for the cars in this question.
