a.) Use linear least squares to find the accelerationof the cart from the speed vs. time data: Use any tool you wish(Excel, MathCAD, calculator). [Of course, you can directly use theequations above, but you would probably find that a bittedious!]
answer in m/s

b.) What is the best estimate of the mass of the cart? inkilograms.

The students add 0.180 N tothe force applied to the cart.

c.) What will the cart’s acceleration be now? in m/s/s.

They now put an additional 0.257 kg mass on the cart (they still havethe extra 0.180 N appliedforce).

d.) What will the cart’s acceleration be now?
4m/s2

e.) How much mass must they now add to the cart to make thecart's acceleration what it was initially? [Note: A negative addedmass means that they must remove mass from the cart.]
5 kg

Use Hooke's Law for this (F = - k s ): Where F is the spring'srestoring force; k is the spring constant; and s is the stretch.The negative sign means the spring's restoring force is oppositethe stretch direction.
You have a plot from weight [N] versus stretch [m]. The data formsa linear trend y = 3.743 * x + 1.28. How much will the springstretch if 56.7 grams is hung on the spring?
[cm]
Answer in centimeters with three significant figures or N/A if notenough information is given to answer. When you calculate youransswer, don't use the negative sign in the Hooke's Law formula.Just know that the negative sign simply denotes the force directionis opposite the stretch (or compression).

has anyone had to do a mastering physics lab based on a basketball?it is called laboratory #1 some of the questions are ....
1. By creating a graph of X position as a function of time, it ispossible to find the X velocity of the basketball. Using thesoftware tools, display this graph and find the best fit line usingthe "Linear Fit" tool. What is the slope of the line? How should weinterpret this slope? The software gives a correlation along withthe best fit line, what does this mean? Is it good or bad?

2. Examine the data to determine the very first value of the YVelocity and the X Velocity. There are two values for velocitybecause the velocity of the basketball has two parts, a vertical(Y) part and a horizontal (X) part. The total velocity must befound be adding these two velocities in a particular way:
V = squareroot( (X Velocity)^2 + (Y Velocity)^2 ) If this remindsyou of the pythagorean theorem, good.
Compute this value and show your work in the box below.

3. Make a graph of the Y Velocity as a function of time. Explain,qualitatively, what this graph says about the vertical motion ofthe basketball.
Thanks!
