As two cars move toward each other, the speedometer of one car reads 57.9 km/h while the speedometer of the other car reads 71.0 km/h. Assume that the speed of light is 88.4 km/h. (a) What is the speed of one car as measured by the driver of the other? (b) What does the classical velocity-addition equation give for the speed of one car relative to the other?

You are driving along the highway at a steady speed of 90 km/h when another car decides to pass you. At the moment when the front of his car is exactly even with the front of your car, and you turn your head to smile at him, do the two cars have equal velocities? Draw a position graph to describe the motion of two cars.

he driver of a car is initially moving at a constant speed of 72.0 km/h when a traffic light turns red. If 0.500 s reaction time is required before the brakes can be applied, what is the distance in meters traveled by the car before it begins to slow down? Average speed 8 Com pute the average speed in m/s of a runner who completes a mile in 4.00 min.

An automobile is traveling on a long, straight highway at a steady 75.0 mi/h when the driver sees a wreck 190 m ahead. At that instant, she applies the brakes (ignore reaction time). Between her and the wreck are two different surfaces. First there is 100 m of ice, where the deceleration is only 1.30 m/s2 . From then on, it is dry concrete, where the deceleration is a more normal 8.00 m/s2 . a). What was the car’s speed...

The speed limit in a school zone is 45 km/h. A driver traveling at this speed sees a child run onto the road 20 m ahead of his car. He applies the brakes, and the car decelerates at a uniform rate of 11.0 m/s2. If the driver's reaction time is 0.55 s, will the car stop before hitting the child?What is the stopping distance of the vehicle?

When the drivers pass each other, the driver of the red car is
to toss a package of contraband to the other driver. To catch the
toss on video, one of the cameras must be set up near the point
where the toss will be made. When “action” is yelled out on the
set, the initial separation between the drivers will be 200 m, the
red car will accelerate from rest at a constant 6.12
