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 been...a) 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 been...a) 4Fb)Fc)2Fd) F/4e)F/2
