HW Friday, 11-22

A&B periods

• FBDs and NET FORCE ONLY!  on Ch 5 Think 'n' Solves
• Don't solve the problem yet, just wrap your head around the situation and forces involved.

E period

• Submit the Think 'n' Solve Test on ITS Learning, check your answers, and redo it to improve your score.
• Keep a separate page of your work to turn in on Monday.

HW Thursday - 11/21

E period

Think n solves, FBDs and Net Force only!

Do not solve.

Do not find accelerations.

Do not collect $200.

A and B periods

Finish block n pulley wksht.

Watch example video

HW Monday, 11-18

All periods

• Block & Pulley Worksheet: page 1, page 2 (if you didn't finish in class)
• Chapter 5 Plug 'n' Chugs 19-23 -- check your answers on Its Learning

HW Friday, 11-15

A & B periods

• Finish lab (if you haven't already)
• Block & Pulley Worksheet: page 1, page 2

E period

• Finish lab

HW Thursday, 11-14

All periods:  Complete the calculations for the lab using the data you now have.

• Measured Acceleration table:
• Average the times for each trial
• Calculate the measured accelerations on page 2 using distance and time (a = 2d / t^2)
• Theoretical acceleration table
• Total hanging mass starts at 0.06 kg and increases 0.01 for each trial
• Calculate the weight of the hanging mass in Newtons  (F = mg, with g = 9.8 m/s/s)
• Total mass is constant (you already figured it out on the previous page)
• Calculate the theoretical acceleration using force and mass ( a = F / m )
