    A barge of mass M = 300 kg is floating on a lake (assume there are no forces between the barge and the water in the plane of the lake and that the water is not moving). The barge is moving at a velocity vo = 0.4 m/s along the +x direction. As the barge floats by, a man of mass m = 90 kg standing at the edge of the lake takes a running start and jumps in the...

    A river flows due east at 2.69 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 12.2 m/s due north relative to the water. What is (a) the magnitude (m/s) and (b) the direction (degrees east of north) of the boat’s velocity relative to shore? (c) If the river is 324 m wide, how far (m) downstream has the boat moved by the time it reaches the north shore?
