Data from three force sensors is recorded in forcetest. csv. the first column is the channel (sensor 0, 1 or 2), the second column is the voltage measurement in volts and the third column is the timestamp of the reading in seconds. a. because the recordings are not exactly synchronized, use a linear interpolation to resample the voltage reading for each sensor between 1 and 17 seconds in increments of 1/120 sec b. the conversion from the voltage reading to force measurement (in newtons) for each sensor is = −32. + 0.2677 = −34. − 1.208 = −36. − 1.993 convert each channel from the measured voltage to the calculated force and plot them all on a single plot against time from 1 to 17 sec. include a legend and axis labels.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
