Question
Objects 1 and 2 are shown below. Object 1 has mass 20 kg, object 2 has mass 9 kg, and the kinetic
coefficient of friction for object 1 on the table is 0.3. If object 1 is pushed so that it is moving away from
the pulley, then find the magnitude of the acceleration of each mass and the tension in the string.

Expert Solution
Step 1

Given 

mass of object 1 m1 = 20 kg

mass of object 2 m2 = 9 kg

kinetic coefficient of friction μ = 0.3

Force of friction is defined as 

F = μN

where N = normal force to the surface.

N =mg
