Extension on Momentum-Impulse Theorem
Today we are finishing up the worksheets that were handed out on Friday and starting an extension of the theorem using Integral Calculus.
For more information click here.
Example: if the time-variant force is F(t) = t^2+2t+6 and you want to know the impulse (momentum change from t=1 to t=4 seconds we must integrate F(t) from 1 to 4
Notice that the area from 1 to 4 is the impulse. You can estimate it right from the graph without even doing the "calculus."
The Wolfram Alpha solution gives: 54Ns (click here to view the solution online)
Dynamics in 2D
Over the next few days we will be working on the following sheets (examples and problem sets). This will lead up to the test evaluation for this mini-review-unit.
Today is the projectile motion competition launch day. I will post details about the angles and distances launched as well as videos from the launches after they are completed.
We are working on our review problems and on the launcher task activity. Test is on Wednesday.
The test will be on Wednesday, March 8, 2017. These review problems will be very helpful to you.
Amazing Projectile Motion Competition
For this activity you will be deriving some complex equations that will allow you to calculate the stretch required (of an elastic attached to a washer - the projectile).
The project due date (and launch day) is on Thursday, March 9, 2017.
