(Newton’s third law)(5.4)Equation 5.4 implies that F12 = F21 . Moreover, this equation holds true regardlessof whether the two bodies move or remain stationary.F21F1212F12 = − F21Fig. 5.1 The force exerted by body 1 on body 2 is equal in magnitude but opposite to the force exertedby body 2 on body 1[r]

dtSolving for a = dv/dt, we get:a=m2 − m1Im1 + m2 + 2Rg=6 kg − 4 kg(9.8 m/s2 ) = 1.87 m/s22 × 10−4 kg.m26 kg + 4 kg +(2 × 10−2 m)2If I is ignored, we get a = (m2 − m1 )g/(m1 + m2 ) = 1.96 m/s2 as proved in Example 5.3 of Chap. 5. Since this value is larger than 1.87 m/s2[r]
