A 50 kg person rows his boat towards the east with 5 N of force. The stream pushes his rowboat to the south with 12 N of force. What is the acceleration of the boat?

Answer:

The acceleration of the boat is:

[tex]a=0.26\: m/s^{2}[/tex]

Explanation:

We need to find the total force acting on the boat, first of all.

We have one force (F1) towards the east and a second force (F2) towards the south, forming a right triangle.

So, we can use the Pythagorean theorem to find the magnitude of the total force (F(tot))

[tex]F_{tot}=\sqrt{F_{1}^{2}+F_{2}^{2}}[/tex]

[tex]F_{tot}=\sqrt{5^{2}+(-12)^{2}}[/tex]

[tex]F_{tot}=13\: N[/tex]

Applying Newton's second law, we can find the acceleration of the boat.

[tex]F_{tot}=ma[/tex]

[tex]a=\frac{F_{tot}}{m}[/tex]

[tex]a=\frac{13}{50}[/tex]

[tex]a=0.26\: m/s^{2}[/tex]

I hope it helps you!
