HW 9-26 Cliff Diving Safety Guide

Legal disclaimer:  Medway does not condone any student jumping off of things to test this activity.  This is a mental exercise only.

Okay, now that that's clear... :)

To determine when to pull their parachute, a base jumper needs to know how high the cliff is and how fast they are traveling to allow enough time.  To determine the height of the cliff, the base jumper drops a rock and waits to hear it hit bottom, counting the time it takes to hit.

Your objective: Create a reference sheet informing them of the instantaneous speed and distance fallen for each second up to 10 seconds.

• Create a table for time (s), velocity (m/s), and distance (m).
• Calculate the final velocity and distance fallen at each second up to 10s.  Show your work for at least one velocity and one distance.  Assume your initial velocity is zero.
• Graph the position-time and velocity-time graphs.

You may create these by hand or using a computer, and work in pairs or alone.

HW 9-24: 2PC 31-33

All periods: Finish up those plug 'n' chugs for chapter 2.
2PC 31-33
means
chapter 2 (page 26), plug 'n' chug problems # 31, 32, and 33
need some help?  read sections 2.5-2.6

In all of these problems, an object is "falling freely" which means we ignore air resistance.
Since it is falling, the acceleration due to gravity = 9.8 m/s/s.  Any time we do labs, we'll want to use this acceleration.  When we do problems, we want to focus on concepts more than exact numbers, so its okay to round this up to 10 m/s/s.

Quiz Reflections

You have your first quizzes back; now its time to focus on what to improve!
As we discussed, we don't do re-takes, we do REFLECTIONS!

Complete a Quiz Reflection to show that you have re-learned some material or improved your skills before the next unit test and improve your quiz grade.  Details are in the document found here.

Focus on points, and you have missed the point.

Focus on learning, and the points will come.
