Inga is walking near the Circular Forest, a forest in the shape of a circle with a radius of 10 km. Inga starts her walk from a point 18 km SOUTH and 9 km WEST of the center of the forest. She walks toward the easternmost part of the forest. When she gets closest to the center, she turns and walks due NORTH. Inga walks at a constant speed of 5.75 km per hour. How much time did she spend in the forest during her walk?

In downtown Chicago, the east-west blocks are 400 ft long while the north-south blocks are 280 ft long. Because of the many one-way streets, it can be challenging to get around. Veronica starts at the corner of Dearborn and Ohio Streets. She drives four blocks north to Superior, two blocks east to Wabash, then a block south to get to her destination at Wabash and Huron. What is the straight-line distance from her starting point?

While exploring a cave, a spelunker starts at the entrance and moves the following distances. She goes 75.0 m north, 250 m east, 115 m at an angle 30.0° north of east, and 185 m south. Find the resultant displacement from the cave entrance. The figure below suggests the situation but is not drawn to scale.

A girl starts from the point A walks 8.0 m east, then 5.0 m south 3.0 m west, and finally 4.0 m to the north to a point B. The displacement from the point A to the point B is?

The highest waterfall in the world is Angel Falls in Venezula, with a total drop of 979 m. Write the height of the falls in cm using scientific notation. i x 104 cm

Cities A and B are connected by a straight road of total length 200 miles.Two cars depart cities A and B at the same time, moving towards each other. The A-car travels at 60 miles per hour, and the B-car at 40 mph. At the same time, a fly starts off from the front bumper of the A-car flying at 100 mph. It flies towards city B until it touches the bumper of the B-car, and then flies back, touches the A-car, flies back, etc, until the cars collide and the fly is squashed. The standard trick question is - what is the total distance traveled by the fly? At first sight one would think that the problem should be solved by the series summation, but that’s not necessary - the cars meet after 2 hours, and during that time the fly traveling at 100 mph covers exactly 200 miles. Now that you know the answer, solve this problem using the series summation [1].

Pls help ASAP

help answer please.

I need help with this practice problem. I was given the answer key but I need help solving it step by step.  A car drives North for 1 km. Then it turns and drives 2 km at 30◦ South of West.Finally the driver turns again and drives 0.5 km Northwest.(a) What is the total distance driven?(b) What are the magnitude and direction of the car’s overall displacement? Answer Key: a.) 3.5 km b.) .11 km, 9.55◦

After conducting the signal speed experiment a student has recorded the following data. L₂ (m) 1.5 3 4.5 8 15 30 dt (ns) 6.50 13.72 21.02 38.10 72.20 145.42 L2 is the length of the longer cable in meters and dt is the measured time delay in nanoseconds. The student neglected to record L₁, the length of the shorter cable. After speaking with their instructor, they learn all is not lost. They know the speed of the signal can be calculated based on the distance traveled divided by the time. However, the recorded times measure how much longer the signal had to travel in L2 compared to L₁. A little bit of thought convinces them (correctly) that
