Three blocks are connected, as shown in the figure below, on a horizontal frictionless table and pulled to the right with a force T3 = 65.0 N. If m1= 12.0 kg, m2= 24.0 kg, and m3 = 31.0 kg, calculate the acceleration of the system
The tensions T1 and T2 in the interconnecting cords.

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
