Question:

What's the force of a boat if it's going if its current is going up 400n and the paddlewheel goes to the right 1000n?

INet Force:

In this problem, we have to find the net force on the boat. However, there is some mistake in this problem. The direction of the current is left and the direction of paddlewheel force is right. We need to calculate the net force. Now, force is a vector quantity, therefore while dealing with forces we have to keep the magnitude and the direction in mind as well.

Answer and Explanation: 1

Force is a vector quantity, it has magnitude as well as the direction.

To solve this problem we will assume the direction towards the right is positive and toward left as negative.

Therefore the force on the boat due to padel is {eq}F_1=1000\ \rm N {/eq}

And the force on the boat due to the current is {eq}F_2=-400\ \rm N {/eq}

Hence the net force on the boat is {eq}F_1+F_2=1000+(-400)=+600\ \rm N {/eq}

Hence the net force on the boat is {eq}600\ \rm N {/eq} towards right.
