5. (ENERGY CONSERVATION) Consider the system shown in the figure below, with two blocks of equal mass m = 2 kg connected by a taut cord over a frictionless pulley, and the leftmost block attached to a spring with spring constant k end of the spring is tethered to the wall. The coefficient of kinetic friction between the = 100 N/m. The other leftmost block and the table is = 1. The system is held with the spring at its relaxed (or equilibrium) length and then released. per m Mk=1/4 m (a) How far does the spring stretch before the blocks come to rest? (b) If the cord connecting the two blocks is then severed, untethering the block on the table to the hanging block, what would be the minimal required coefficient of static friction (us) between the block and the table in order for the block on the table to remain stationary?

A group collected data in an experiment to learn to draw suitable trendline in a graph. They don't know the theoretical model, so they are trying to determine one through this experiment. They used Excel to display the data and to find good fit. They tried linear, exponential, and power trendlines. The result of each trial is shown below. The title of the plot contains the name of the trendline used to fit. What should be their analysis based on the result they have so far? Exponential trendline 20 Power trendline 18 y = 0.8374e047x R? = 0.9851 16 y = 0.8045x1.538. R2 = 0.981 15 14 12 10 10 ..... 4 ..... ....... 2 1 3 4 1 7 Linear trendline 20 y = 3.0209x - 4.6606 15 R? = 0.9293 10 ........ 2 4 6 8 The linear trendline is good fit The exponential trendline is good fit Any one of the three trendlines seems good candidate The power trendline is the best fit 2. 2.
