Chapter 2, Problem 94GP
You are traveling at a constant speed vM, and there is a car in front of you traveling with a speed vA. You notice that vM > vA so you start slowing down with a constant acceleration a when the distance between you and the other car is x. What relationship between a and x determines whether or not you run into the car in front of you?

You are driving your car along a country road at a speed of 27.0 m/s. As you come over the crest of a hill, you notice a
farm tractor 25 m ahead of you on the road, moving in the same direction as you at a speed of 12.0 m/s. You immediately
slam on your brakes and slow down with a constant acceleration of magnitude 8 m/s2. Will you hit the tractor before you
stop?
Ο NO
O Yes

Situation 03. A Ford Territory and a Montero Sport are traveling in the same direction at 60.0 kph
on a straight highway, parallel to each other, and the Territory is ahead of Montero by 248.90 kph. At
a certain time, Territory decelerates uniformly at 2.50 m/s², whereas the Montero accelerates
uniformly at 2.0 m/s2.At what distance measured from the initial position of Montero will it overtake
Ford Territory.
Situation 04. The acceleration of a particle moving along a straight line is a = Vs, where s is in
meters If its nosition s-0 and velocity v-0 when it is at rest
You are in your car at an intersection waiting for the traffic light to turn green. When it turns
green, you drive your car at a uniform acceleration of 3.20 m/s². At the same time, a motorcycle
traveling at a constant speed of 20.0 m/s overtakes and passes you.
a. How far from the intersection point will you overtake the motorcycle?
b. How fast are you traveling when you overtake the motorcycle?

You immediately apply your brakes and skid straight to a stop, leaving a 100 ft long mark from the landslide. A policeman observes the whole incident, give the driver of the car a ticket for running a red light. He also gives a ticket to you for exceeding the 30 mph speed limit. When you get home, you read your physics book and you may notice that the coefficient of kinetic friction between the tires and the road was 0.60, and the coefficient of static friction was 0.80. You estimate that the hill makes an angle of about 10° with the horizontal. Check the manual owner and find that your car weighs 2,050 lbs. Are you going to claim the traffic ticket? in the court?
