Question

Two boxes, A and B, are connected by a (mass-less) cord andare resting on a smooth (frictionless) table. The boxes have massesof 12.0 kg and 10.0 kg. A horizontal force (Fp) of 40.0N is applied to the 10.0kg box. (a.) Find the acceleration of each box. (b.) Find the tension force in the cord connecting the twoboxes.

Explanation / Answer

the system is accelerated by the force Fp. N2 Law: F=ma a=F/(m1+m2)=40N/(10kg+12kg)=1.818m/s2 part b: Force need to accelerate the secondmass=m2*a=12*1.818=21.816N therefore the tension is 21.816N part b: Force need to accelerate the secondmass=m2*a=12*1.818=21.816N therefore the tension is 21.816N
