What is the acceleration of the three boxes

Reference no: EM13338721

Three boxes are being accelerated on a horizontal table with a 60-N force applied to box 1 at an angle 35o below the horizontal. (see figure) The bottom of box 1 and 3 experience no friction with the table surface. The coefficient of kinetic friction between box 2 and the table is 0.15. The mass of box 1 is 10 kg, the mass of box 2 is 5 kg, and the mass of box 3 is 20 kg.

(a) Draw a free-body diagram for each box separately, identify all of Newton's 3rd law force pairs.

(b) Find the normal force the table exerts on each box separately.

(d) Draw a free-body diagram for the three box system.

(e) What is the acceleration of the three boxes?
