Question1

Two boats, each capable of moving in still water at a constant velocity v = 6 m/s, place out to cross a river of width W = 20 m. Boat 1 heads directly across the river while boat 2 is pointed at an angle q = 60 degrees with respect to the. The current in the river moves at speed v0 = 2 m/s as shown.

Which boat takes the least amount of time to cross the river?

Boat 1 takes the least time.

Boat 2 takes the least time.

Each boat takes the same amount of time.

Which boat moves with the greater speed with respect to the shore?

Boat 1 moves with greater speed with respect to the shore.

Boat 2 moves with greater speed with respect to the shore.

They both move at the similar speed with respect to the shore.

How far downstream (D) is boat 2 when it reaches the other side of the river?

D = 7.1 m
D = 7.9 m
D = 10.0 m
D = 14.6 m
D = 19.3 m
