3/20/12

Today we did LOTS of kinematics practice using the College Prep Packet--Numbers 47, 16, 18 and 19.

You can see my work for #47 here.

Remember for #16 you are just calculating speed and velocity but you need to convert the km to m FIRST and min to seconds FIRST.

Remember for #18, you are calculating displacement over time for EACH chunk of the graph (or....slope :) rise over run) and REMEMBER that displacement has DIRECTION so one of those parts has a negative displacement.

Remember #19, you are calculating DISTANCE over time for each chunk (speed) AND displacement over time for each chunk (velocity)--REMEMBER displacement has direction.......
