For Wednesday's class

This homework is related to the discussion we had in class about horizontal motion vs. vertical motion. A baseball is thrown horizontally at 30 m/s (which is a pretty typical Park pitcher throwing speed).  It leaves the pitcher's hand 1.5 m above the ground. 1. How long would the ball take to hit the ground, if it does not hit a bat (or anything else) first?  Keep in mind this is just like a dropped object, since there is no horizontal acceleration for the ball (after it leaves the pitcher's hand). 2.  How far will the ball travel horizontally in this time.  Hint:  use v = d/t (since there is no horizontal acceleration). 3.  Is there any time difference between this thrown ball and another ball dropped from the same height (instead of thrown)?  Discuss why. 4.  Challenge question.  If the pitcher were standing on a 0.5 m tall mound,  but otherwise throws as above, how long would the ball take to touch ground and how far would i...

HW related to pendulum lab

1.  Graph period of ONE swing (T, in seconds) vs. length (L, in meters).  T will be on y-axis and L will be on x-axis.  Make certain that length is converted to meters (if you used cm). 2.  Print out graph. 3.  Make a third column of data - square root of each length measurement (in meters). 4.  Think/write about this:  What makes a simple pendulum "simple"?  What is assumed to be true about the simple pendulum? 5.  If you have the video from the giant swing, try to determine the period of one oscillation (one complete swing of the person).  We are going to try to compare theoretical pendulums to the giant swing in our next class.
