As two trains move along a
track, their conductors suddenly notice that they are headed toward
each other. The figure gives their velocities v as a function of
time t as the conductors slow the trains. The figure's vertical
scaling is set by vs = 37 m/s.The slowing process begins when the
trains are 168.00 m apart. What is their separation when both
trains have stopped?

As two trains move along a track, their conductors suddenly
notice that they are headed toward each other. The figure gives
their velocities v as a function of time t as the
conductors slow the trains. The figure's vertical scaling is set by
vs = 23.0 m/s. The slowing processes
begin when the trains are 122 m apart. What is their
separation when both trains have stopped?

As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The figure gives their velocities v as functions of time t as the conductors slow the trains. The figure's vertical scaling is set by vs 48.0 m/s. The slowing processes begin when the trains are 240 m apart. What is their separation when both trains have stopped? t (s) Number TT96 Units m
