Utilitarism..

If I see a man standing on a bridge and below the bridge are 5 workers repairing the bridge and there is an uncontrolled car in direction to smash them so all would die..and if I would have a possibility to press a button so this one guy standing on the bridge would fall down,die but stop the car. 1 life for 5 lifes. Would that be the right thing to do? (sheep if you are reading this,you know what I mean..)
