Two forces, of magnitudes F1
= 60.0 N
and F2
= 30.0 N
, act in opposite directions on a block, which sits atop a frictionless surface, as shown in the figure. (Figure 1)Initially, the center of the block is at position xi
= -6.00 cm
. At some later time, the block has moved to the right, and its center is at a new position, xf
= 5.00 cm
.
