Use the pythagorean theorem to answer this question. a paper airplane is thrown westward at a rate of 6 m/s. the wind is blowing at 8 m/s toward the north. what is the actual velocity of the airplane?
2 m/s, northwest
10 m/s, northwest
14 m/s, northwest
48 m/s, northwest

The correct answer to the question is : 10 m/s , northwest.

EXPLANATION:

As per the question, the velocity of wind V = 8 m/s towards north.

      The velocity of the paper airplane is V' = 6 m/s towards west.

We are asked to calculate the actual velocity of the airplane.

By putting Pythagorean theorem, the actual velocity of the airplane is calculated as -

                ⇒  

                ⇒  

                ⇒  

                ⇒    towards northeast.

Hence, the correct answer is 10 m/s , northwest.              

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

thermal energy is the answer
