Car A starts from rest at t=0 and travels along a straight road with constant acceleration of 6 ft/s2 until it reaches a speed of 80 ft/s. Afterwards it maintains this speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 60 ft/s. (a) Determine the distance travelled by car A when they pass each other. (b) Determine the distance travelled by car B when they pass each other. (c) Determine the time travelled by car A and car B when they pass each other.

Traveling with an initial speed of 70 km/h, a car accelerates at 6000km/hr2 along a straight road. How long will it take to reach a speed of120 km/h? How far did the car travel during this time?
If you divide the total distance traveled on a car trip (as determined by the odometer) by the elapsed time of the trip, are you calculating average speed or magnitude of average velocity? Under what circumstances are these two quantities the same?
A runner with a good awareness of her pace runs along a path of unknown length at a speed of 0.275 mi/min and then walks back to her starting point at a speed of 0.0500 mi/min. She neglects to note her time for each part of her path, but does measure the total round trip time to be 60.0 min. How far did she run? Do not include the walking distance
A deer is running east to west on a straight line. It runs (a) at a constant speed of 2.5 m/s for the first 24 sec, (b) at a reduced speed (also constant) of 0.6 m/s for the next 15 sec, (c) sprints at a constant speed of 3.1 m/s for the next 1 minute and 40 seconds. Compute the total distance covered and the average speed in mph.
A train is traveling down a straight track at 32 m/s when the engineer applies the brakes, resulting in an acceleration of −1.0 m/s2 as long as the train is in motion. How far does the train move during a 64-s time interval starting at the instant the brakes are applied in meters?
Ferrari LaFerrari can go from zero to 120 miles per hour in 6.5 seconds. Assuming that it can keep its acceleration constant, how long a distance can it cover in 15 minutes? Express the answer in metric units. (1 mile is equal to 1.61 kilometers) Hint: Obtain the acceleration from the first setence.
A simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.2 m/s in 2.14 s, what will be his total time?
Two cars travel in the same direction along a straight highway, one at a constant speed of 55 mi/h and the other at 60 mi/h. Assuming they start at the same point, how much sooner does the faster car arrive at a destination 6 mi away? How far must the faster car travel before it has a 15-min lead on the slower car?
One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.1 m/s in 2.54 s, what will be his total time?
A car is traveling at 96 km/h when the driver sees an accident 75 m ahead and slams on the brakes. What minimum constant deceleration (in m/s2) is required to stop the car in time to avoid a multi-car pileup? (Round your answer to two decimal places.)
On a two-lane road, car A is travelling with a speed of 72 km/h. Two cars B and C approach car A in opposite directions with a speed of 108 km/h each. At a certain instant, when the distance AB is equal to AC, both being 2 km, B decides to overtake A before C does. What minimum acceleration of car B is required to avoid an accident ?
A hypothetical spaceship takes a straight-line path from the Earth to the moon, a distance of about 400,000 km. Suppose it accelerates at 10.0 m/s2 for the first 20 minutes of the trip, then travels at constant speed until the last 20 minutes, when it accelerates at -10.0 m/s2, just coming to rest as it reaches the moon. What total time in minutes is required for the trip?
