Two blocks connected by the string are being pulled to the right across a horizontal
frictionless surface by another string. The strings are horizontal and their masses are
negligible compared to those of the blocks. The tension in the string connecting the
blocks is 0.05 kN.
(a) Draw a free-body diagram for each block.
(b) Find the tension in the rightmost string if the mass of the right block is three times
that of the left block.
(c) What are the forces (magnitude and direction) exerted on a surface by the two blocks
if their acceleration has a magnitude of 4 m/s2?
The numerical results are
b)Tright = 200N i
c) F1= -367.5 N j; F2 = -122.5 N j
