You are arguing over a cell phone while trailing an unmarked police car by 27.0 m. Both your car and the police car are traveling at 100 km/h. Your argument diverts your attention from the police car for 2.30 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.30 s, the police officer begins emergency braking at 5.00 m/s². (a) What is the separation between the two cars when your attention finally returns? x m (b) Suppose that you take another 0.400 s to realize your danger and begin braking. If you too brake at 5.00 m/s?, what is your speed when you hit the police car? km/h

You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground. How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway? Express your answer using one significant figure.
A suspicious-looking man runs as fast as he can along a moving sidewalk from one end to the other, taking 2.50 s.Then security agents appear, and the man runs as fast as he can back along the sidewalk to his starting point, taking 10.0 s.What is the ratio of the man’s running speed to the sidewalk’s speed?
An auto travels going to Roxas City at a rate of 25 km/hr for 0.045 hour , then at 50 km/hr for 0.056 hr, and finally at 20 km/hr for 0.015 hour. Find the total distance covered in km and the velocity for the complete trip.
The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)?
A jetliner can fly 4.8 hours on a full load of fuel. Without any wind, it flies at a speed of 2.68 x102m/s. The plane is to make a round trip by heading due west for a certain distance, turning around, and then heading due east for the return trip. During the entire flight, however, the plane encounters a 69.9 m/s wind from the jet stream, which blows from west to east. What is the maximum distance that the plane can travel due west and just be able to return home?
how much time would it take you to cover the61-m length of the walkway if, once you get on the walkway, youimmediately turn around and start walking in the opposite direction with a speed of 1.3 m>s relative to the walkway?
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model? Figure P3.42

What is the size of angle θ and what is time of flight of the ball?a. θ = 17.223⁰, t = 8.44 sb. θ = 19.372⁰, t = 4.6 sc. θ = 18.263⁰, t = 9.3 sd. θ = 16.273⁰, t = 7.3 s
A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times: (Enter your two answers separated by a comma. Round to ONE decimal places.)
A rocket is fired upward with a velocity (v) of 590 feet per second. find how many seconds pass before the rocket reaches the ground (s=0) again. use the quadratic equation s=-16t^2+590t.
An unidentified flying object (UFO) is observed to travel a total distance of 49000 m, starting and ending at rest, over a duration of 3.07 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. 20,796 g s 10,398 g s 2,120 g s 1,060 g s
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?
