Second+Project

=Second Project - Newton's Second Law and Free Body Diagrams=

You have a second project with your team. Please join the wiki if you have not done so since there is no alternative assignment.

Post something each day from what we have done in class. Each team member should post so pick a day for each person to post

Examples include:

how to calculate the magnitude and direction of vectors that are part of a free body diagram Examples: Finding the applied force when net force is known.
 * Elevator problems
 * Rocket launch problems
 * kinematics with acceleration
 * kinematics with acceleration
 * kinematics with acceleration

A bowling ball with a mass of 4.24 kg is acted on by an external force that reduces its velocity from 8.5m/s to 4.1 m/s in 3.0 sec. What is the magnitude of the retarding force? Vo= 8.5 m/s 4.1-8.5/3 X 4.24 kg = 6.22 m/s^2 Vf= 4.1 m/s t= 3.0 s
