This week in Physical Science we will conclude our discussion of kinematics with some examples of momentum; we will then continue our discussion of Newton’s laws. We will also run our velocity lab later in the week.
As a reminder, students should come to class with the following materials every day:
- A calculator
- A whiteboard marker
- Their notes so far from this quarter
- A pencil
- Their agenda
For up to 10 points of extra credit, students can hand in a written response to the following questions:
On a recent launch, the first stage of the Falcon 9 spacecraft accelerated from rest to 4700 mi/hr in 2.5 minutes.
- What was the average acceleration (in m/s²) of the rocket during this time?
- What was the average acceleration in g’s (Earth gravitational g’s, not grams)?
All work and any relevant formulae must be shown. The calculations and answer should be on a separate sheet of paper from the textbook homework due tomorrow.
