Deflection of ball down ramp from path

`qx001.  How far did the ball travel after leaving the end of the ramp, in the trial without the magnet, and what therefore was its horizontal velocity during the fall, assuming a fall time of .4 second?

****

#$&*

`qx002.  What is the maximum deflection of the ball, due to the presence of the magnet, from its original straight-line path?

****

#$&*

`qx003.  What velocity does the ball therefore attain, in the direction perpendicular to its original straight-line path, as a result of the magnet?

****

#$&*

`qx004.  Assume the ball was close enough to the magnet to have its motion significantly influenced for a distance of 5 centimeters.  How long did it take for the ball to travel this distance?

****

#$&*

`qx005.  Assume that the ball has a mass of 60 grams.  How much momentum did it gain, in the direction perpendicular to its original line of motion, as a result of the magnet?

****

#$&*

`qx006.  What therefore was the average rate of change of its momentum with respect to clock time, for the 5-cm interval during which the magnet significantly affected its motion?

****

#$&*

`qx007.  What were the measurements by which you can calculate the slope of your ramp?  What was the slope of the ramp?

Acceleration of gravity

`qx008.  What was your count for the object dropped in the stairwell?  To what time interval in seconds does your count correspond?

****

#$&*

`qx009.  What was your count for the object dropped in the stairwell?  To what time interval in seconds does your count correspond?

****

#$&*

`qx010.  What was the distance the object fell (1 block = 8 inches or about 20 centimeters)? 

****

#$&*

`qx011.  Using the distance of fall and the time interval in seconds, find the acceleration of the falling object.

Ball off ramp to floor, at angle:  University Physics Students Only

`qx012.  Find the initial velocity of the falling ball, based on your measurements of x, y, x0, y0 and your determination of sin(theta) and cos(theta).

****

#$&*

`qx013.  Find the time of fall of the ball.

****

#$&*

`qx014.  Questions about uncertainties:

• What is your estimated uncertainty in the measurements you used to determine sin(theta)? 
• What therefore is your uncertainty in sin(theta)? 
• What uncertainty does this introduce into your determination of v0?

`qx015.  Based on a single trapezoid of the graph of F vs. x for magnet forces, explain the meaning of the slope and the area of this graph.

`qx016.  Based on a single trapezoid of the graph of PE vs. x for magnet forces, explain the meaning of the slope and the area of this graph.
