A 463g wood block is given a quick push across a table. During the push it accelerates at a rate of +0.49m/s^2, but after the push it slows to a stopwith an acceleration of -0.73m/s^2,Assuming the frictional force was the same strengthboth during and after the push, what was the strength of the force used to push the block to start with?

Imagine a 4.0-kg wood block sliding across a horizontal table surface with a positive velocity and an acceleration of -2.0 m/s. You need to calculate the coefficient of kinetic friction for these two surfaces. 1. Start the same way you always should whenever you have a question involving forces and accelerations. Draw a free-body diagram (arrows for all the forces, arrow for net force, and a coordinate system) for the block. All the forces, vertical as well as horizontal. 2....
