Question
Two identical blocks, A and B, are initially at rest on
a level, frictionless surface. At time t = t 1 , hands
begin to push the blocks toward each other as shown
at right. Each hand exerts a constant horizontal force
of magnitude Fo . At time t = t 2 , each block has moved
a distance d o from its initial position.
is the work done on block A positive or negative? Block B?
what is the net work?
