A train normally travels with a uniform speed of 72 km / h on a long stretch of flat, straight track. On a certain day, the train must make a 2.0 minute stop at a station on this track. If the train decelerates with a uniform rate of 1.0 m/s^ 2 and after stopping, it accelerates with a rate of 0.50 m/s^ 2. How much time will it have lost by stopping at the station?

A driver, driving at a constant speed of 30m/s in a 50 mph zone, is unaware that he is being observed by an approaching police car (coming toward him from the front). At time t = 0, they are 800m apart and the police car has an approach speed of 40 m/s. When will the police officer catch up with the motorist? a) 80 s b) 68.6 s c) 11.4 s
A train is traveling down a straight track at 20 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 40-s time interval starting at the instant the brakes are applied?
An unidentified flying object (UFO) is observed to travel a total distance of 19000 m, starting and ending at rest, over a duration of 4.23 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.
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?
A car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
As soon as a traffic light turns green, a car speeds up from rest to 50.00 mi/h with constant acceleration 9.00 mi/h/s. In the adjoining bicycle lane, a cyclist speeds up from rest to 20.0 mi/h with constant acceleration of 13.00 mi/h/s. Each vehicle maintains constant velocity after reaching a cruising speed. For what time interval is the bicycle ahead of the car?
A jet plane comes in for a landing with a speed of 100 m/s, and its acceleration can have a maximum magnitude of 5.00 m/s^2 as it comes to rest, from the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
As an airplane is taking off at an airport its position is closely monitored by radar. The following three positions are measured with their corresponding times: x1 = 145.50 m at t1 = 3.10 s, x2 = 185.00 m at t2 = 3.60 s, x3 = 229.50 m at t3 = 4.10 s. What is the acceleration of the airplane at t2 = 3.60 s? (Assume that the acceleration of the airplane is constant.) What is the average velocity of the airplane during the first time interval? What is the average velocity of the airplane during the second time interval?
A commuter train travels between two downtown stations. Because the stations are only 1.00 km apart, the train never reaches its maximum possible cruising speed. During rush hour the engineer minimizes the time interval t between two stations by accelerating at a rate a1 = 0.100 m/s2 for a time interval t1 and then immediately braking with acceleration a2 = 0.500 m/s2 for a time interval t2. Find the minimum time interval of travel t and the time interval t1.
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 person takes a trip, driving with a constant speed of 89.5 km/h, except for a 22 minute rest stop. If the persons average speed is 77.8 km/h how much time is spent on the trip and what distance did they travel?
An object is subject to a constant acceleration of 4.16 m/s2 in the positive x direction. If it is initially at rest, what is its displacement in the x-direction at t = 8.99 s?
