12-17

Hello Physics class. This is "The Physics Journalist" for December 17th.

Today in class we did a Daily Question. We were asked to find the value of A, B and C. Click the link below to see the original Daily Question. [|DQ:12/17] __To find A:__ Use the Pythagorean theorem- Take the sum of 3.9 squared and 32.6 squared and set it equal to x squared. Solve for X. You should find that the hypotenuse(X) is approximately equal to 32.8 meters. __To find B:__ Remember that Tanget is equal to Opposite over Adjacent. Take the tangent of B and set it equal to (32.6 over 3.9). Then take the inverse tangent of (32.6 over 3.9) and set it equal to B. Plug that into your calculator. You should find that the angle measure of B is approximately 83.2 degrees. __To find C:__ Again, take the tangent of C and set it equal to (3.9 over 32.6). Then take the inverse tangent of (3.9 over 32.6) and set it equal to C. Plug that into your calculator. You should find that the angle measure of C is approximately 6.

Then we proceeded to review the answers to page 23 which was our classwork and homework from Tuesday. We went over the answers to number one in class. Listed below are the answers to numbers 2 and 3.

2) a. V= 103.92 m. Q= 60 m. b. M= 109.97 m. P= 63.02 m. c. W= 574.53 cm. Z= 482.1 cm. d. S= 188.4 miles R= 313.03 miles

3) a. X= 83.82 m. (theta symbol)= 17.35 degrees b. Y= 541.20 m. (theta symbol)= 33.63 degrees

For the remainder of the period we worked on page 24 which we picked up on our way into class today. We will go over the answers tomorrow.

Reminder: Test on Friday.

Peace :)
