Exam 3 (cont.) 19. 8 of 12 Consider two carts of mass m and 4m, at rest on a frictionless, horizontal surface. Now suppose a horizontal force is exerted on each cart. The forces are constant, and they have the same magni- tude F, and the same direction. The force on m acts for 2 seconds and the force on 4m acts for 1 second. After the forces cease, the carts continue moving with constant velocity forever. Compare the momenta...

on string 1, which is attached to block A. Block A is also attached
to block B via string 2, as shown.
For this problem, assume that neither string stretches and that
friction is negligible. Both blocks have finite (nonzero) mass.

relationship between the accelerations of blocks A and
B?
