Just as a car starts to accelerate from rest with acceleration 1.4 m/s2, a bus moving with a constant speed of 12 m/s passes it in a parallel lane. How long before the car overtakes the bus? How fast will the car then be going? How far will the car then have gone?
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?
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
While driving down a straight road at 70.5 km/h, you pass your physics professor who happens to be out for a jog. He's running at a constant 4.00 m/s, and you decide to slow down and talk physics with him. If you apply your brakes exactly when you pass him on the road, and your car accelerates at 3.58 m/s2 during the breaking, how far do you end up going before he catches up to you?
An express train passes through a station that is 220 m long. It enters with an initial speed of 22.5 m/s and decelerates at a rate of 0.14 m/s2 as it goes through. During what time interval, in seconds, is the front of the train within the station? How fast is the train moving, in meters per second, when its front leaves the station? If the train is 130 m long, how long, in seconds, after the front of the train enters the station does the end of the train leave the station? What is the velocity of the end of the train as it leaves in m/s?
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.)
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 police car, sitting at the side of the road is passed by a car driving a constant 60 m/s. If the police car can accelerate 2.5 m/s2, how long will it take for the police car to reach the speeding car?
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 commuter is driving a car along a straight road at a constant speed of 15.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 3.50 m/s2 to overtake her. Assume that the officer maintains this acceleration. What If? Determine the answers to parts (a) through (c) of the problem, if instead of accelerating at the same instant the car passes him, the officer instead begins his acceleration 1.00 s after the car passes him. (Enter the time in s, speed in m/s, and displacement in m.) time s speed m/s displacement m
An express train passes through a station that is 212 m long. It enters with an initial speed of 22.5 m/s and decelerates at a rate of 0.13 m/s2 as it goes through. During what time interval, in seconds, is the front of the train within the station? If the train is 120 m long, how long, in seconds, after the front of the train enters the station does the end of the train leave the station? What is the velocity of the end of the train as it leaves in m/s?
The first supersonic flight was performed by Charles Yeager in 1947. During his attempt, he flew from 119 m/s to top speed, accelerating at 7.29 m/s^2 for a distance of 5251 m. What top speed did he achieve?
