A vehicle crash between a 1000. kg car and an 1800. kg truck takes place on a 72000. N bridge that is 50.0 m long and supported at each end

by a pillar. The collision takes place at the center of the bridge where the initial velocity of the car is 5.000 m/s east the initial velocity of the truck's 2.000 m/s west. As a result of the collision, the car and truck connect bumpers and slide off together along the frictionless bridge surface. What force must each pillar exert upward 22.00seconds after the collision
