M A woman with mass m = 9 kg is at the back end of a flatboat with mass M = 60 kg and length L = 6 m floating on water. Initially, the L woman and the flatboat are at rest and the distance from the front end of the flatboat to the pier is d = 2m. The woman starts to run towards the pier with speed v, = 1 m/s relative to the flatboat. Assume that the boat moves without friction on water. A) What is the velocity of the runner with respect to the pier in units of m/s? B) What will be the distance (in units of meters) between the front end of the flatboat and the pier when the runner reaches the front end? E
