1) A Ford Mustang can accelerate from 0 to 60 mph in a time of 5.2 s. A Mini Cooper isn't capable of such a rapid start, but it can turn in a very small circle 36 ft in diameter. How fast would you need to drive the Mini Cooper in this tight circle to match the magnitude of the Mustang's acceleration?

2) Mary needs to row her boat across a 100 m-wide river that is flowing to the east at a speed of 1.5 m/s. Mary can row the boat with a speed of 2.0 m/s relative to the water. If Mary rows straight north, how far downstream will she land?

3) A boat takes 4.0 hr to travel 36 km down a river, then 6.0 hr to return. How fast is the river flowing?
