3. A boat at sea is being moved by the ocean current at 5 metres/minute directly to the east. At the same time it is being moved directly to the north at 3 metres/minute by a strong wind. Determine the magnitude and direction of the boat's overall velocity.

Explanation:

A boat at sea is being moved by the ocean current at 5 metres/minute directly to the east.

At the same time, it is being moved directly to  the north at 3 metres/minute by a strong wind.

We need to find the magnitude and direction of the boat's overall velocity.

As both velocities are moving perpendicular to each other. The resultant velocity is given by :

For direction,

Hence, this is the required solutin.

measure their densities same density, same sub

the inner core.

good luck: )
