Two cars are driving at the same constant speed on a straight road, with car 1 in front of car 2. Car 1 suddenly starts to brake with constant acceleration and stops in 10 m. At the instant car 1 comes to a stop, car 2 begins to brake with the same acceleration. It comes to a halt just as it reaches the back of car 1. What was the separation between the cars before they starting braking?

A police car is traveling in a straight line with a constant speed "Vp". A truck traveling in the same direction with the speed "3*Vp/2" passes the police car. The truck begins to slow down (the moment it passes the police car) at a constant acceleration of "-a" until it comes to a stop. Then the police car passes the truck. What is the maximum velocity the truck can have, so that the police car will reach him before he...

Problem 4 A car travels along a straight road at a speed of 20 m/s, it decelerates uniformly to a stop over a period of 30 seconds; the car then it travels in the opposite of the original direction accelerating uniformly to a speed of 30 m/s in that direction over a period of 15 seconds a) Prepare a scaled time-velocity graph. b) Prepare a scaled time-acceleration graph. c) Prepare a scaled time-distance traveled graph. d) Determine average velocity of...

Two cars are traveling along a straight line in the same direction, the lead car at 25.7m/s and the other car at 29.2m/s. At the moment the cars are 39.7m apart, the lead driver applies the brakes, causing her car to have an acceleration of -1.99m/s2. How long does it take for the lead car to stop? 1.29×101 s What is the distance it travels during this time? 1.66×102 m Assuming that the chasing car brakes at the same time...

D Question 10 1 pts You are driving on a straight road at exactly 26 miles per hour when you see a child run out in front of your car,chasing a ball. You push the brakes hard, which results in an acceleration of exactly-36000 miles/hour? The child freezes in panic and you cannot swerve to avoid the child because there are cars parked on both sides of the street. How many feet does your car travel before it comes to...
