Problem 2 Here on Earth, where the acceleration due to gravity is 9.8 m/s² straight down, a person pushes a 10 kg cubic block across a table by applying a horizontal force of magnitude 25 N. Kinetic friction opposes the applied force and the block accelerates at a rate of 1.2 m/s². What must be the coefficient of kinetic friction for the pair of materials comprising the block and the table?

Problem 2
Here on Earth, where the acceleration due to gravity is 9.8 m/s² straight
down, a person pushes a 10 kg cubic block across a table by applying a
horizontal force of magnitude 25 N. Kinetic friction opposes the applied
force and the block accelerates at a rate of 1.2 m/s². What must be the
coefficient of kinetic friction for the pair of materials comprising the block
and the table?
