The spool and wire wrapped around its core have a mass of 20 kg and a centroidal radius of gyration kg = 250 mm. if the coefficient of kinetic friction at the ground is = 0.1, determine the angular acceleration of the spool when the 30 ∙ m couple moment is applied. express your answer using three significant figures and include the appropriate units.

Write the correct abbreviation for each metric unit

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
