. What is the best way to determine levelness OR What isthe best way to determine when the slope of the glider track iszero?
1. See if the Acceleration versus Time for both directions areboth zero.
2. Plot Position versus Time and compare the linear fit fromeach direction of travel; slopes should be equal.
3. Plot the Acceleration versus Time for one direction andacceleration should be zero.
4. See if slope of Velocity versus Time for both directions areequal but opposite.
5. Plot Position versus Time and compare the linear fit fromeach direction of travel; slopes should be equal but opposite.
6. Plot Velocity versus Time for both directions; slopes shouldbe equal.

(a) Plot v(f)^2 versus D on graph paper.
(b) What is graph slope? What about units? what does it
represent?
Since the glider starts from rest, the initial velocity
vi is equal to zero. Thus vf2 =

Vibrational Motion Introduction If an object is following Hooke’s Law, then Fnet = -kx = ma Since acceleration is the second derivative of position with respect to time, the relationship can be written as the differential equation: kx = m δ2xδt2/{"version":"1.1","math":"<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>k</mi><mi>x</mi><mo> </mo><mo>=</mo><mo> </mo><mi>m</mi><mo> </mo><mfrac bevelled="true"><mrow><msup><mi>δ</mi><mn>2</mn></msup><mi>x</mi></mrow><mrow><mi>δ</mi><msup><mi>t</mi><mn>2</mn></msup></mrow></mfrac></math>"} Methods for solving differential equations are beyond the scope of this course; in fact, a class in differential equations is usually a requirement for a degree in engineering or physics.

A fully-loaded tractor-trailer rig itself also costs the company an average of $1.25/mile to operate (for fuel, maintenance, insurance, etc.). distant To monitor the safety and whereabouts of drivers and cargo, each truck is equipped with a GPS tracker, which transmits a continuous (second-by-second) record of the truck's position; and a speedometer recorder, which transmits a continuous record of its speed (in mph).
