A car is initially moving with a velocity of +6.0 m/s and travels for 8.0 s with the uniform acceleration of +2.0 m/s^2. the driver then applies the brakes, causing a uniform acceleration of 4.0 m/s^2. the brakes are applied for the 2.0. A. Find the car's speed at the end of the braking period. B. How far has the car traveled during the whole process?
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 ?
Cars A and B are traveling at vA=116 km/hr and vB=108 km/hr respectively when the driver of Car B applies the brakes abruptly causing the car to slide to a stop, see Figure Q1. Take the coefficient of friction for the road to be 0.8. Suppose the driver of Car A takes 1.5 seconds to react to the situation and applies his brakes causing Car A to slide as well. Given Car A has the same deceleration as Car B calculate the minimum distance, d between A and B at the time Car B starts sliding, to avoid a car crash.
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 car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t) = bt^2-ct^3, where b = 2.40 m/s^2 and c = 0.120 m/s^3. a) Calculate the average velocity of the car for time interval t = 0 to t = 10.0 s. b) Calculate the instantaneous velocity of the car at t = 0, t = 5.0 s, and t = 10.0 s. c) How long after starting from rest is the car again at rest?
A box was dropped from the top of a building. Which of the following is true regarding its displacement per second? (A) The distance covered by the falling box per second increases. (B) The distance covered by the falling box per second decreases. (C) The distance covered by the falling box per second remains constant. (D) I need more details to confirm any of these three statements.
The distance S that an object falls varies directly with the square of the time t. If an object falls 16 feet in one second, how long for it to fall 400 feet? The time required to drive a fixed distance varies inversely as the speed. It takes 1 hr at a speed of 400 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?
Colonel John P. Stapp, USAF, participated in studying whether a jet pilot could survive emergency ejection. On March 19, 1954, he rode a rocket-propelled sled that moved down a track at a speed of 632 mi/h. He and the sled were safely brought to rest in 1.40 s. (a) Determine the negative acceleration he experienced (in m/s2). answer: -202m/s^2 (b) Determine the distance he traveled during this negative acceleration (in m). answer: 198 m (c) What If? Col. Stapp was able to walk away from this experiment. If the human body can survive a negative acceleration five times that experienced by Col. Stapp, what minimum stopping time (in s) would this correspond to in the 1954 experiment? ______________s

Automotive engineers refer to the time rate of change of acceleration as the jerk. Assume an object moves in one dimension such that its jerk J is constant, (a) Determine expressions for its acceleration ax(t), velocity x(t), and position x(t), given that its initial acceleration, velocity, and position are axi, xi, and xi, respectively, (b) Show that ax2 = axi2 + 2J(x xi).
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.
