In the figure, the light, taut, unstretchable cord B joins block 1 and the larger-mass block 2 . Cord A exerts a force on block 1 to make it accelerate forward.
(1)
(a) How does the magnitude of the force exerted by cord A on block 1 compare with the magnitude of the force exerted by cord B on block 2 ? Is it larger, smaller, or equal? larger:
smaller
equal
(b) How does the acceleration of block 1 compare with the acceleration (if any) of block 2 ?
larger
smaller
equal
(c) Does cord B exert a force on block 1 ? If so, is it forward or bsckward? Is it larger, smaller, or equal in magnitude to the force exerted by cord B on biock 2?
