The following are two dimensional motion problems. Use the equations of motion in both the x and y directions to solve. Refer to the figure below: In the problem above, the velocity of the boat, vb, is m/s.
The velocity of the current, vc is m/s.
The width of the river is m.

1) With what total (resultant) speed does the is boat move?
m/s

2) How long does it take the boat to reach the other side of the river?
seconds

3) How far does the boat move horizontally along the river in this time. (What is the horizontal distance from where the boat starts to the large X?)
m
