Answer 1

Answer: Nope

Explanation:

The car can turn safely only when its centripetal force is≤ frictional force                          in this case centripetal force is  greater than frictional force ,which can be concluded from the given equation :                                                                               mv²/r⇒ centripetal force                                                                                            mu ×  mg⇒ frictional force
