(Student section 730) PHY231C, Spring 2017 In troductory Physics Homework set e4 (due 2/7 at 1:59PM) Stacked Blocks pret Inte Two masses M 4.40 kg and M 9.10 kg are stacked on top of each other as shown in the figure. The static coefficient of friction between M1 and M2 is us 0.340. There is no friction between M2 and the surface below it. M1 M2 Whaf is the maximum horizontal force that can be applied to M2 without M1 sliding relative to M2 Submit Answer Tries 0/20 Send Feedback Post Discussion

Explanation / Answer

Since the blocks slides with same acceleration
F- s*m1*g=m2a .......(1)
also,
F=(m1+m2)a
a=F/(m1+m2) put in 1

F- sm1g=m2*F/(m1+m2)
F(m1+m2)-m2F=(m1+m2) sm1g
F=(m1+m2) sm1g/m1
=(m1+m2)s*g
=(4.4+9.1)*0.340*9.8
= 45 N
