10-23

October 23

Unfortunately, Mr. Manning was very sick on this day, so we had a substitute. The substitute was Mr. Comi... good times. Mr. Comi gave us a packet (pgs. 34-41). We worked on this packet the entire period. The instructions from Mr. Manning were as follows: 1) Read the packet 2) Label numbers in the problem as a velocity (final or initial), acceleration, displacement, or time 3) Make a graph for each problem

__**IF YOU ARE CONFUSED**__ Here is problem #1: Michael Johnson was jogging around the track on day at 4.0 m/s, when his coach told him to pick up the pace. At that time (which we'll call t=0.0 s), Michael accelerated at 2.0 m/s/s (m/s^2) for 4.0 s to reach his final speed. 1) You've already read the packet     2) Label numbers in the problem as a velocity (final or initial), acceleration, displacement, or time: 4.0 m/s = initial velocity 2.0 m/s/s = acceleration 4.0 s = time 3) Make a graph:                My computer has no drawing programs.  I tried my hardest to scan, but that didn't work for me either.  The graph has a y-intercept of 4.0 m/s and goes in a line up to the right, ending at 4 sec (time on x graph, velocity on y graph).

So we worked on this packet so we will be prepared for class when Mr. Manning returns. Elizabeth Young
