10. A person is driving along a straight highway at a speed of 22.0 m/s when the traffic light which is 43.0 m ahead turn yellow. Because of his "reaction time", there is a delay of 0.15 s before the man steps on the brake. The car then slows with a deceleration of 4.20 m/s2. By how much distance does the driver miss the traffic light line? m coll6?

You are driving your car along a country road at a speed of 23.6 m/s. As you come over the crest of a hill, you notice a farm tractor 25.0 m ahead of you on the road, moving in the same direction as you at a speed of 10.0 m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 7.20 m/s2.       How far is the tractor in front of you when you finally stop?

While driving at 45.0 mi/hr (20.1 m/s) on a straight portion of Route 9 West, Randi notices that the traffic light has turned red at the intersection directly ahead. Randi applies his brakes, slows his car down at a steady rate, and brings his car to rest, while traveling the 60.0 m distance to the stop line (at the red light). 21. While he is slowing down, the acceleration of Randi's car has a magnitude of A. 6.73 m, В. 16.9 m 2. 169 m/: А. С. 33,8 т D. 9.80 m E. 3.37 m / 22. How much time passes as Randi's car slows down from 45.0 mi/hr to 0 m/s? A. 20.68 s. B. 5.97 s. C. 2.66 s. D. 2.99 s. E. 0.596 s. 23. While Randi's car is slowing down, his car's acceleration is A. directed straight down towards the Earth's center. B. equal to zero. C. directed straight upwards. D. directed parallel to the car's velocity. E. directed antiparallel to the car's velocity.

*85. D mmh A police car is traveling at a velocity of 18.0 m/s due north, when a car zooms by at a constant velocity of 42.0 m/s due north. After a reaction time of 0.800 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s². Including the reaction time, how long does it take for the police car to catch up with the speeder?

An object moves so that its position depends on time as x=+12m-(4m/s)t+(1m/s^2)t^2. Which statement is not true?

b. A car traveling at a constant speed of 33.5 m/s passes a trooper hidden behind a billboard. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.30 m/s2. How long does it take the trooper to overtake the speeding car? Solve this problem by a graphical method. -On the same graph, plot position versus time for the car and the trooper. -From the intersection of the two curves, read the time at which the trooper overtakes the car.  (seconds)

*34. o mmh A race driver has made a pit stop to refuel. After refueling, he starts from rest and leaves the pit area with an acceleration whose magnitude is 6.0 m/s°; after 4.0 s he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant velocity of 70.0 m/s overtakes and passes the entering car. The entering car maintains its acceleration. How much time is required for the entering car to catch the other car?

You are driving down a straight road at night in your McLaren MCL34 Formula 1 racecar at an entirely illegal speed of 98 m/s when Bambi and Thumper jump onto the road in front of you. Because you were texting while driving (also illegal), your reaction time is a rather slow; 1.3 seconds before your foot touches the brake. How far did you travel during this time? O a. 98 m O b. 127 m O c. 101 m O d. 134 m O e. 112 m Clear my choice

3. A quarterback throws a football with initial velocity components Voy= 10.0 m/s (upward) and Vax = 19.0 m/s (down the field). It is caught at the same height it is thrown from. a. How long does it take for the football to reach its maximum height? b. How high is this point above where the ball was released? c. How much time, after it was thrown, elapses before the ball is caught? Compare this time to what you found in part (a). d. How far away from the quarterback is the ball when it is caught? 4. Repeat question 3, but have the initial speed of the ball be 28.0 m/s and the initial angle be 38.0° up from horizontal.
