Determine the time it takes to slow down

Reference no: EM13666345

A 1000 kilogram boat travels across a lake when its engine is shut off. Magnitude of friction between water and boat is proportional to boat's speed (proportionality constant is 70). Determine the time it takes to slow down to one half its original speed when the engine is shut off.
