Question

4. Two blocks of masses m, and ma are placed in contact with each
other on a frictionless horizontal surface as shown in Fig. 1.33. A
constant horizontal force is applied to the block of mass m1
Determine the acceleration of the two block system and force

Answer 1

Answer:

Method 1 :  

Since the two blocks always remain in contact with each other, they must move with the same acceleration. Using Newton's second law, we get
