A box slides across a frictionless horizontal surface with constant acceleration 3.40 m/s2 and over a time interval reaches a final velocity of 13.0 m/s.

a. If its initial velocity is 6.50 m/s, what is its displacement (in m) during the time interval?

b. What is the distance it travels during this interval?

c. If its initial velocity is -6.00 m/s what is its displacement during the time interval?

d. What is the total distance it travels during the interval in part (c)?

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
