Sept. 26 – Projectile Motion Problems

Announcements

Here's the plan for next week:
  • Monday: Work Period
  • Tuesday: Formative Quiz
  • Wednesday: Review day, Lab Due (period 2)
  • Thursday: Test day, Lab Due (Period 5)
  • Friday: Thinking Question


Today I worked out some full solutions to projectile motion problems.  Look at this one involving Milos Raonic serving a ball from the top of the CN tower:






The second question involved this golfer:


The video tells us that the ball went 279 yards (we'll make it meters!).  We timed it to find that ∆t = 6.6 s.  We were then able to calculate the initial speed and angle of the hit.  See the full solution above.

In period 5, I also showed the full solution to number 3 of this problem set:



Homework



  • Work on your lab write up.
  • Work on day 11 homework from the Unit Outline.
