Ranjeet parks his car in a lot on the corner of Park Lane and Main Street. He walks80 m east to First Avenue, turns 30° to the left, and follows First Avenue for 100 m tothe Metro Building, where he takes the elevator to his office on the 15th floor. Eachfloor in the building is 4 m in height. From his office window, Ranjeet can see his carin the lot. How far is Ranjeet from his car, in a straight line? At what angle ofdepression is Ranjeet looking to see his car?

I took 2.28km and converted it to 2280 meters then divided by 3200 and ended up with .71m/s but it keeps saying that its incorrect. Im not sure where I keep messing up. John walks 1.80 kmkm north, then turns right and walks 1.40 kmkm east. His speed is 1.60 m/sm/sduring the entire stroll. What is the magnitude of his displacement, from beginning to end? (2.28) If Jane starts at the same time and place as John, but walks in a straight line to the endpoint of John's stroll, at what speed should she walk if she wants to arrive at the endpoint just when John does?
Mr. M is walking to Mr. T’s house. He takes a short cut across an open field. His first displacement is 140m [E35N]. He then walks 200.0m [E]. What is Mr. M’s total displacement? (320m [E14N])
During her recent trip to the grocery store, Claire walked 14m,North to the end of an aisle. She then made a turn and walked 6m, 30o N of E. Finally, she made another turn and walked 8m, S. Determine the magnitude of Claire's resultant displacement and direction.

27. Two bicyclists, starting at the same place, are riding toward the samecampground by two diff erent routes. One cyclist rides 1080 m due east and then turns due north and travels another 1430 m before reaching thecampground. The second cyclist starts out by heading due north for 1950 mand then turns and heads directly toward the campground. (a) At the turning point, how far is the second cyclist from the campground? (b) In whatdirection (measured relative to due east) must the second cyclist headduring the last part of the trip?
1.) A street light is mounted at the top of a 15-ft-tall pole. A man 6 feet tall walks away from the pole with a speed of 7 ft/s along a straight path. How fast (in ft/s) is the tip of his shadow moving when he is 45 feet from the pole? ________ ft/s 2.) Two cars start moving from the same point. One travels south at 32 mi/h and the other travels west at 24 mi/h. At what rate (in mi/h) is the distance between the cars increasing four hours later? ________ mi/h 3. Question (a) is already solved. Please solve question (b). (a) If A is the area of a circle with radius r and the circle expands as time passes, find dA dt in terms of dr dt . dA dt = 2πr dr dt (b) Suppose oil spills from a ruptured tanker and spreads in a circular pattern. If the radius of the oil spill increases at a constant rate of 2 m/s, exactly how fast (in m2/s) is the area of the spill increasing when the radius is 33 m?…
Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!
