Two separate seismograph stations receive indication of an earthquake in the form of a wave traveling to them in a straight line from the epicenter and shaking the ground at their locations. Station B is 70 km due east of station A. The epicenter is located due north of station A and 60 ∘ north of due west from station B. A) Determine the distance from the epicenter to A. Express your answer using two significant figures. B) Determine the distance from the epicenter to B. C) Station C is located an additional 30 km east of B. At what angle does C report the direction of the epicenter to be? Express your answer using two significant figures.

Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.20×106 N, one at an angle 19.0 ∘ west of north, and the other at an angle 19.0 ∘ east of north, as they pull the tanker a distance 0.710 km toward the north. What is the total work done by the two tugboats on the supertanker? Express your answer in joules, to three significant figures.

Two geological field teams are working in a remote area. A global positioning system (GPS) tracker at their base camp shows the location of the first team as 39 km away, 13° north of west, and the second team as 31 km away, 36° east of north. When the first team uses its GPS to check the position of the second team, what does the GPS give for the following? (a) the second team's distance from the first team____ km...

Two cars collide at an intersection. Car A, with a mass of 1800 kg , is going from west to east, while car B , of mass 1300 kg , is going from north to south at 16 m/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle...

Monroe County is trying to determine where to place the county fire station. The locations of the county’s four major towns are as follows: (10, 20), (60, 20), (40, 30), and (80, 60) (see Figure 7.50). Town 1 averages 40 fires per year; town 2, 25 fires; town 3, 20 fires; and town 4, 30 fires. The county wants to build the fire station in a location that minimizes the average distance that a fire engine must travel to respond...
