A 10 N force is applied on the 3 kg block. What are the accelerations of the 2 kg block, 3 kg block and 7 kg block? Take the value of g=10m/s^2.
what is the acceleration of each of the block ?
Source of question : HC VERMA ,CHAPTER 6,Question 23
maximum value of static friction between m2 and m3 =15 N
maximum value of static friction between m1 and m2 =4 N
applied force = 10 N
considering the surface between m2 and m3
applied force on m2 =10N < 15 N ; no relative motion between m2 and m3.
considering the upper surface m2 and lower surface of m1
applied force on m2 =10N > 4 N ; there is relative motion between m2 and m1.
acceleration of m1 = force/2 = (maximum value of static friction)/2 = 4/2 = 2 m/s^2
acceleration of m3 = force/7 = (value of static friction)/7 = 10/7 m/s^2.
since there is no relative acceleration between the surface of m2 and m3,acceleration of m2 = that of m3= 10/7 m/s^2.
