Bomber Problems and Graphs
Movie • Watch the movie and then answer questions #1 & #2.
QuickTimeª and a H.264 decompressor are needed to see this picture.
Hey Answer the questions on the worksheet! • You should complete the front side of the worksheet before continuing.
Check your horizontal graphs

The horizontal motion is constant so you have no acceleration.
Check your vertical graphs v

The vertical motion is accelerated motion. The value for the ay vs t graph would be -9.8 m/s2.

DON’T MOVE ON • UNTIL YOU HAVE ACTUALLY DONE THE BACK!!!
YOU DID FINISH THE BACK • RIGHT?
Ok, Now let’s check you answers #1 &2) You should have found that all the times were the same. Remember the horizontal velocity has no effect on the time of fall. The bigger the horizontal velocity the farther it will travel.
Answers to #3 • • •
The horiz. velocity doesn’t change because ax=0. The vert. velocity increases because its accelerating downward (from gravity). The actual velocity is getting more and more downward. The actual velocity actual points tangent to the path and would be gotten from adding the two components together. (Sorry the tangents aren’t drawn perfectly.)
Answers to #4 a) The only force acting is gravity and gravity only affects the vertical. b) The vert. acceleration vector stays the same because “in a vacuum, all objects fall with the same constant acceleration”.
