b. A boat starts to cross the river which is 2.0 km wide. The boat travels at 20 km Ir' relative to the surface of the water and points directly across the river. The river is moving at 6.0 km h' downstream relative to the river bank. 1) What is the boat's velocity relative to the river bank? (2 m) ​

To calculate the boat's velocity relative to the river bank, apply vector addition rules with the given velocities to find the resultant velocity and direction.

Explanation:

The boat's velocity relative to the river bank can be calculated using vector addition.

Given boat velocity = 20 km/h and river velocity = 6.0 km/h downstream, we must find the resultant velocity.

By applying vector addition rules, the boat's velocity relative to the river bank is about 22.8 km/h at an angle of 16 degrees upstream from the y-axis.
