Coming to the bottom of a mountain, a skier moving with speed v collides with a barrier and is brought to a stop in an amount of time t. over the course of the impact, the skier experienced an average net force f from the barrier. if the skier\'s initial velocity had been the same (v), but the time of impact to come to a full stop had been four times as long (4t), what would have been the average net force exerted on the skier during the collision? the average net force would have ) f/4b)fc)4fd) f/2e)2fif the time of impact to come to a full stop had been the same (t), but the skier\'s initial velocity had been half as much (v / 2), what would have been the average net force exerted on the skier during the collision? the average net force would have ) 4fb)fc)2fd) f/4e)f/2
