Concluding Momentum and Newton’s Laws this week in Physical Science

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:

  1.   A calculator
  2.  A whiteboard marker
  3. Their notes so far from this quarter
  4. A pencil
  5. 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.

  1. What was the average acceleration (in m/s²) of the rocket during this time?
  2. 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.
