The skier leaves from point A from rest and slides on the frictionless track AB, then he continues his motion on the track BCD; under the action of a frictionless force of constant magnitude = ; to stop at D. Consider the skier to be a point object during its motion. Given: g = 10 m/s2 .

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
