1. What is the maximum speed with which a
1200-kg car can round a turn of radius 80.0 m on a flat road if the coefficient
of friction between tires and road is 0.65? Is this result independent of the
mass of the car?

2. Is it possible to whirl a bucket of
water fast enough in a vertical circle so that the water wonÂ’t fall out? If so,
what is the minimum speed? Define all quantities needed.
