A woman stands in a boat at rest on a calm lake. She throws a 10 kg anchor off the front of the boat, which has a mass of 1,000 kg. a. What is the initial momentum of the anchor-boat system?
b. In which direction will the boat move after the anchor is thrown?
c. How does the change in momentum of the anchor compare to the change in momentum of the boat?
d. If the velocity of the anchor is 12 m/s, what is the velocity of the boat after the anchor is released?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
