This morning I was driving down a narrow residential street with cars parked on either side, and plenty of un-plowed snow. Just as I was passing a car going the opposite direction, some dumb bitch in a parked minivan about one car length in front of me opened her driver's door and got out of the vehicle. I SLAMMED on the brakes while she went deer-in-headlights and stared at me bearing down on her. My truck stopped about two feet from her...feet.
People, don't be ignorant. Look in your mirror before swinging your door open and jumping out on the street. Doesn't matter that I'm only going 10kph, it's a fricken pickup truck on snow. It's gonna slide. Think about your safety before leaping out into traffic you bunch of morons.

A pick up truck who's mass is equal to 2,495 kg is being driven by 4x4 who weighs 82 kg. It is traveling down a snow and ice covered road at a constant speed of 10km/h. A woman one car length (8 m away) in the direction of travel steps out of her car into the road. Assuming that it takes 4x4 1 second to react and apply the brakes (assume the tire and road coefficient of friction = 0.06), calculate how long it will take him to come to a complete stop and how far from the woman will he stop.
