52. A highway engineer is using a road map to lay out a detour for the westbound lane of a section of highway that, on the map, is a straight line going east and west. On the map, the detour goes 4 miles straight north, 1 mile straight west, 2 miles straight north, 6 miles straight west, 3 miles straight south, I mile straight east, and finally 3 miles straight south, back to the highway. According to the map, how many more miles will a westbound driver travel by taking the detour than he would if he could stay on the highway? F. 20 G. 14 Н. 13 12 J. K. 6.

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 130 km and 25.0 of west, then 5.10 km due east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?
In 1999, Robbie Knievel was the first to jump the Grand Canyon on a motorcycle. At a narrow part of the canyon (69.0 m wide) and traveling 35.8 m/s off the takeoff ramp, he reached the other side. What was his launch angle?
You wish to get to Target to purchase “high-quality” goods. To get toTarget from your current location, Google tells you to walk in a straightline for 1.35 km at an angle of 40.0◦south of east. Before going to Target,however, you want to grab a slice of pizza and then get some coffee. Thepizza place is 0.54 km from you at an angle of 60.0◦south of west. Fromthe pizza parlor, you must walk 2.1 km due east to get coffee. Just afteryou buy coffee, your phone dies. Use your understanding of vectors todetermine how far and in which direction you should walk to get to Target.
An airplane leaves the runway heading south and flies for 2000km. It then heads 20 degree west to avoid a storm. After flying for 500km, it turns 40 degree toward the east and flies another 400km to its final destination. Calculate the displacement of the plane;s destination and the distance it travelled.
1. A boy walks 20 m west, 12 m in direction of 30 degrees north of west and 40m in direction of 60 degrees south of west in 5 minutes. Determine magnitude and direction of his average velocity.
21. If a biker rides west for 50 miles from his starting position, then turns and bikes back east 80 miles. What is his displacement? O 130 miles O 30 miles east O 30 miles west Cannot be determined from the information given
horse wander thriugh beak in baryard fence and wanters 34 m at 60.1 north of east. then 21m east. what is the magnitude of horse displacement. round to one decimal
Mr. Brown takes a walk in the park. He first travels 600. m NW and then turns and walks 800. m @ 20.0° WoS. What is his overall displacement of his walk? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer, I just don’t know how to get it. Answer: 771 m @ 25.1° SoW Thanks!!
ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A train is travelling east along a straight run of track at 66 km/hr. Inside, two siblings 2.2 m apart are playing catch directly across the aisle. The kid wearing a PJ Harvey T-shirt throws the ball horizontally north. The ball crosses the train and is caught 1.2 s later by their little sibling. (Ignore any effects of gravity or friction.) Find the magnitude of the ball's velocity in m/s from the little brother's point of view. What is the magnitude of the velocity (in m/s) of the ball as seen by someone standing still outside the train? What is the angle (in degree) that a stationary observer would say the ball makes during the throw, relative to the direction of the train?
You take a three-day hiking. On the first day, you travel 5.0 km heading East. On the second day you’ve enjoyed the scenery so much that you forgot to take note how far you have walked and in what direction. On the third day, after wandering for 8.5 km and in the direction 37o South of West, you find yourself in the base camp where you have started (which means the total displacement is zero). Determine your displacement during the second day of your trip.
Erica is participating in a road race. The first part of the race is on a 2.6-mile-long straight road oriented at an angle of 25∘∘ north of east. The road then turns due north for another 2.0 mimi to the finish line. In mies, whats is the straight line distance from the starting point to the end of the race?
1110. In Fig. P-1109, a ball thrown down the incline strikes it at a distance s 254.5 It. If the ball rises to a maximum height h 64.4 ft above the point of release, compute its initial velocity vo and inclination 6. Ans. v. = 80.5 ft per see; 0= 53.1° FIG. P-1109 and P-1110.
