you can express the vector a+b as two vectors, one horizontal and one vertical. Which is the horizontal. please use the \hat{i} or \hat{j} notation. you can do that using typing in \hat

Question 5

5.

Rosa Boat is paddling upstream at 1.4 m/s relative to the water in a river which is flowing at 0.50 m/s relative to the banks of the river. which diagram shows the resultant velocity of Rosa's boat (relative to the banks)?

If the boat is going 1.4m/s relative to the river, you would add the vectors, she would be going faster than she thinks because the water is carrying her faster than she is rowing.

if she is paddling upstream, she is going the opposite way the river is flowing. and if she is going 1.4 m/s relative to the water, it means she is going less quickly than she thinks relative to the bank.

her total speed is the difference between her speed and the river speed, but since the river is going backwards, you would add the magnitudes.

The river is flowing downstream, so even though she is paddling the wrong direction, it isn't strong enough for her to move upstream.

Rosa's boat is paddling upstream at 125 cm/s relative to the water in a river which is flowing at 50 cm/s relative to the banks of the river. What is the resultant velocity of Rosa's boat (relative to the banks)?
