A 1000 kg boat is traveling at 90 km/h when its engine is shut off. The magnitude
Question:
A 1000 kg boat is traveling at 90 km/h when its engine is shut off. The magnitude of the frictional force f k between boat and water is proportional to the speed v of the boat: fk = 70v, where y is in meters per second and fk is in new tons. Find the time required for the boat to slow to 45 km/h.
