A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 5.11 m/s. The car is a distance d away. The bear is 34.0 m behind the tourist and running at 7.01 m/s. Both the bear and the tourist are running with constant velocity. What is the maximum possible value for d in meters for the tourist reaches the car safely?
a driver sees a deer in front of his car about 100.0 meters in front of him. the driver was traveling 50.0m/s before applying the brakes and coming to rest right where the deer was. what acceleration did the driver experience? answer in m/s2?
Some troublemaking kids are dropping water balloons from the roof of your apartment building. You are in your ﬁfth-ﬂoor room and your window is 25 m above the sidewalk outside. You look outside and see that each balloon hits the pavement 1.5 s after passing your window. Express answers using 2 signiﬁcant ﬁgures. a) How fast are the balloons traveling when they pass your window? b) Assuming the balloons are being released from rest, from what height above your window are they being released? c) If you threw a balloon upwards from your window with an initial speed of 6.5 m/s, would you be able to get it to the roof?
Maria needs to travel to her sister's home, 285 km away, in 4.0 hours. The first 60 km she can only travel at 40.0 km/ hr. What will her average speed need to be for the remainder of the trip in order to make it in time?
A physics student at a track meet has a radar gun which she can use to measure the speeds of the runners. Shortly after the start of one race she measures that the speed of a runner is 1.57 m/s. When the runner is 11.2 meters farther along the track, she measures the runner’s speed to be 7.87 m/s. Determine the runner’s acceleration during this interval (assuming the runner’s acceleration is constant)?
Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
A police car gets passed by a car traveling at a constant speed of 150.0 km/hr. The police car accelerates from rest at 5.00 m/s2, the moment the two cars are side by side. How long does it take the police officer to catch the car?
An airplane is initially traveling with a velocity of 55.0 m/s due east when a gust of wind causes the airplane to have an acceleration of 40.0 m/s² due north. What is the airplane's new total speed after 6.0 s? [Hint: Draw a picture.] O 174.6 m/s O 55.0 m/s O 184.4 m/s O 262.5 m/s O 246.2 m/s
A red Mazda Miata (type of car) accelerates from rest at a rate of a₁ in the positive x direction for a total of 20.0 seconds. The Mazda then holds their speed and direction constant for a 20.0 additional seconds. Finally, while continuing in the positive x direction, the Mazda slows down at a rate of a2 until the car stops moving. We want to determine the total distance traveled by the Mazda and the average speed of the car if we know a₁ and ₂. (A) Sketch a graph of velocity versus time for this short trip. Label the time axis to indicate which portions of the curve(s) correspond to the above intervals. Identify and write knowns and unknowns (B) Without using numerical values, determine which physics equations of motion will help solve this problem. Simplify as useful for this particular case. (C) If a₁ = 2.0 m/s² and a₂ = -3.0 m/s² determine the total distance traveled during all intervals and the average velocity of the Mazda.

A car is moving towards the left, which is the negative X direction. It travels 49.2 m during a 7.83-s time interval. What is the cars average speed in meters per second during the time interval?
Car A was traveling east at high speed when it collided at point O with car B , which was traveling north at 45 mi/h. Car C , which was traveling west at 60 mi/h, was 32 ft east and 10 ft north of point O at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they hit the utility pole p. Knowing that the weights of cars A, B, and C are, respectively, 3000 lb, 2600 lb, and 2400 lb, and neglecting the forces exerted on the cars by the wet pavement, solve the problems indicated.Knowing that the coordinates of the utility pole are xp= 46 ft and yp = 59 ft, determine (a) the time elapsed from the first collision to the stop at P,(b) the speed of car A.
