A police car traveling at 95.0 km/h is traveling west, chasing a motorist traveling at 80.0 km/h. (a) What is the velocity of the motorist relative to the police car? (b) What is the velocity of the police cat relative to the motorist? (c) If they are originally 250 m apart, in what time interval will the police car over take the motorist?
A distance with two significant figures divided by a time interval with three significant figures equals an average speed. How many significant figures does the average speed have?
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?

A moving beltway at an airport has a speed 1 and a length L. A woman stands on the beltway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the beltway with a speed of 2 relative to the moving beltway. (a) What time interval is required for the woman to travel the distance L? (b) What time interval is required for the man to travel this distance? (c) A second beltway is located next to the first one. It is identical to the first one but moves in the opposite direction at speed 1. Just as the man steps onto the beginning of the beltway and begins to walk at speed relative to his beltway, a child steps on the other end of the adjacent beltway. The child stands at rest relative to this second beltway. How long after stepping on the beltway does the man pass the child?
The engineer of an intercity train observes a rock slide blocking the trains path 225.0 m ahead and activates the trains emergency brakes. The train decelerates uniformly at 1.8 m/s2 for 12.70 s before reaching the rock slide. What is the speed with which the train reaches the rock slide?
(a) A light-rail commuter train accelerates at a rate of 1.35 m/s2. How long does it take to reach its top speed of 80.0 km/h, starting from rest? (b) The same train ordinarily decelerates at a rate of 1.65 m/s2. How long does it take to come to a stop from its top speed? (c) In emergencies the train can decelerate more rapidly, coming to rest from 80.0 km/h in 8.30 s. What is its emergency deceleration in m/s2?
Two cars leave Seattle at the same time en route to Boston on Interstate 90. The first car moves uniformly the whole way, with constant speed v. The second car travels with constant speed (v + 1) mph for the first half of the distance and travels with constant speed (v 1) mph for the second half of the distance. Which car gets to Boston first (or is it a tie)? Explain your reasoning.
2. A motorist saw a humps 33 m away at a speed of 14.5 m/s. He immediately slams on the brake and decelerates 1.2 m/s 2 with a speed of 11.7 m/s. (a) Will he stop before the humps (express your answer in magnitude)? (b) How long it will take before stopping?

A player using a cue accelerates a shuffleboard disk at a constant 7.3m/s2 from rest for 0.65sec. At this point the disk loses contact with the cue and slows down at a constant rate of 2.3 m/s2 until it stops. What is the total distance traversed by the disk?
Hello, I had a physics question. "Just as the traffic light changes to green, a Mustang drives through the intersection at a constant velocity of 14.2 m/s [N]. A Camaro that was stopped at the light accelerates from rest at 2.9 m/s^2 [N]. How much time passes before the two cars meet again? How far have they travelled? I figured out how to do the question but I'm really confused on the units of the distance. I used the d = v/t formula and the vit + 1/2at^2 formula but the units I ended up getting were m^2/s^3 for distance when it should just be m.
