We started off the day with a graded daily question-- A catapult fires a pumpkin at 30 mi/hr in 130 degree direction. Using trig, calculate how fast the pumpkin was traveling when fired horizontally and vertically. Reference angle= 50 degrees, use cos and sin to solve.   30 mi/hr.

 50’ 130’

Tomorrow is the test on vectors- Remember your PROTRACTOR!

We got 2 papers- Vector Review Problems and More about Vectors. This is what we did for the rest of the period, in preparation for tomorrow's test. We will not be learning any new material until the break is over. Happy Holidays!
