TODAY DAY 26
Today's Goal: 1) To know what is expected of pulleys, friction and the lab.2) To figure out the coefficient of friction and how it is used.
Homework: Given out today for next class. A lot done in class to make sure that we are capable.Importance: Reading situations and knowing what is asked and how to approach it.
Which of these is true for the amount of imbalance in the system?
A) Its 20N, the weight of the hanging mass
B) Its 80N, the weight of the mass on the table
C) Its 100N, both weights added for the system weight
D) Its 60N, the weights subtracted

Which of these is true for the amount of mass in the system?
A) Its 20N, the weight of the hanging mass
B) Its 80N, the weight of the mass on the table
C) Its 100N, both weights added for the system weight
D) It is none of these
Which of these is true for the amount of mass in the system?
A) Its 20N, the weight of the hanging mass
B) Its 80N, the weight of the mass on the table
C) Its 100N, both weights added for the system weight
D) It is none of these
The system mass is the masses added, which is 10kg.
Determine the amount of acceleration and submit it
Which of these is true for the amount of imbalance in the system?
(More than 1 can be right)A) We need to determine the mass in kilograms
B) We need to multiply each by gravity to eventually get weight
C) We need to add both weights together for imbalance
Which of these is true for the amount of imbalance in the system?
(More than 1 can be right)A) We need to determine the mass in kilograms
B) We need to multiply each by gravity to eventually get weight
C) We need to add both weights together for imbalance
We need to subract both weights together for imbalance
DETERMINE THE ACCELERATION
THE LAB:
For next class: Submit on a separate paper.
2 parts, each with what is stated in the GOAL and ANALYSIS
Take 10 minutes
FROM THE VIDEO
FRICTION
Direction:
Equation: Units:
Coefficient of Friction:
For the following picture, 2 people are pulling Kim Kardashian (83 kg I believe). If the coefficient of friction is .4, what is the acceleration of Kim?
First, lets determine the amount of friction.

Now determine the imbalance, then acceleration
NOW LETS TRY
