A 1000kg boat is traveling at 90km/h when its engine is shut off. The magnitude of frictional force acting between the boat and the water is proportional to the speed of the boat and is given by 70vwhere the speed of the boat in meters per second is v. find the time required for the boat to slow down to the speed of 45 km/h.
