(10%) Problem 8: Two blocks connected by a string are pulled across a horizontal surface by a force applied to one of the blocks, as shown to the right. The mass of the left block m1 = 1.3 kg and the mass of the right block m2 = 3.1 kg. The angle between the string and the horizontal is = 61° The coefficient of kinetic friction between the blocks and the surface is u= 0.22. Each block has an acceleration...

1. Two blocks are connected by a string. Block A is pulled by another string so that it moves across a table with increasing speed. The mass of block A is less than that of block B. Assume that: o the strings are massless and inextensible there is friction between the blocks and the table String 2 String 1 How does the acceleration of block A compare to the acceleration of block B? Discuss both magnitude and direction. Explain a....
