Here you'll compare actual and interpolated values from your data and explain any differences you observe. Part A First, record some data for this comparison in the table below. . Record your measured values of displacement and velocity for times t = 8.0 seconds and t = 10.0 seconds in the columns below. . Next, use the measured displacement and velocity values at t = 7.0 seconds and t = 9.0 seconds to interpolate the values of displacement and velocity at t = 8.0 seconds. . Use the following formula to interpolate and extrapolate. Remember, x and y here represent values on the x and y axes of the graph. The x values will really be time and the y values will be either displacement (x) or velocity (Vx). y - yo = (31 -30) (1-20) X (x - 20) BIU X X 2 10pt Velocity (Vx) Quantity Displacement (x) meters meters/second 7 9 Characters used: 68 / 15000
