The boat is moving at a speed of 2.0 m/s when crossing the river.
Step 1: Determine the boat's velocity in relation to the river by deducting the river's current from the boat's speed in still water.
Boat speed in relation to the river is equal to 8.0 m/s minus 6.0 m/s, or 2.0 m/s.
In Step 2, multiply the boat's angular velocity to the stream by both the lake's current to determine how fast the sailboat will be traveling across the water.
Boat's river crossing speed is calculated as 2.0 m/s plus 6.0 m/s, which equals 8.0 m/s.
Because of this, the boat is moving at 8.0 m/s as it crosses the river.
An object's mass and the force being exerted towards it both affect how quickly it moves. The speed of an object's movement increases with increasing force. It will travel more slowly the more mass an object has. This is so that the item can be accelerated by the pressure towards the extent that the mass permits.
