Part E Problem: Thinking and Investigation 44. In testing a new material to be used in non-slip door mats. Scientists made a mat made of this new material, and did the following experiment. A force (F) was used to pull a wooden block across the mat as shown below.(5) m μ The size of the force was varied and the data table below shows the size of the force and the block's resulting acceleration. F(N) (m/s²) 20 0.25 25 0.85 30 1.35 35 1.95 Plot the data on the graph below and draw a line of best fit. Extend the line back to the 'y' axis so that you have a y-intercept point and determine the slope of the line. F (N) The industrial standard for the coefficient of friction for non-slip mats is 0.85. a) Using your slope value and your y-intercept value from the graph, determine the coefficient of friction between the block and the mat. b) Would this mat be approved for production based on its coefficient of friction?

A cannon is fired horizontally from a platform (see figure). The platform rests on a flat, icy, frictionless surface. Just after the shell is fired and while it is moving through the barrel of the gun, the shell (mass 2.9 kg) has an acceleration of +2600 m/s². At the same time, the cannon has an acceleration of -0.72 m/s². What is the mass of the cannon? kg Cannon shell Ice
