uhhh... in my physics class we never learned how to deal with acceleration varying =/ so...
there is a 1000kg boat that turns off its engine and starts cruising along at 25m/s. the drag of the boat against the water is directly proportional to the speed v of the boat, where F is in Newtons: F=70v. how long does it take the boat to slow down to 12.5 m/s?
