Sarah and Bob depart from the bus stop. Sarah walks north for 10 meters and then east for another 30 meters. Bob walks south at some unknown constant speed, vB, for ∆t = 10 seconds
Draw a clear coordinate system, and then on it draw Bob’s and Sarah’s paths.
Find and plot the displacement vectors for both Sarah and Bob
Find the speed, vB, (in km/hour) with which Bob would need to walk if Sarah and Bob were to end up 50 meters from each other.
Please show all steps / pictures

Keith walks north with a constant speed and it takes him 7.00 minutes to walk 0.588 km. Then he turns back and walks south at the same speed for 10.0 minutes. a.) Draw a diagram showing his path. Label the path length of each leg o the journey. Draw the total displacement vector on the diagram. b.) What was the total elapsed time (in seconds) for Keith's journey? c.) what was the path length (in meters)? d.) what was the...
Physics 213 Offline 1 Name: Show your work. Your final answers should have the correct number of sig figs units, and a box around them. (10 points) 1. Keith walks north with a constant speed and it takes him 7.00 min to walk 0.588 km. Then he turns back and walks south at the same speed for 10.0 min. a) Draw a diagram showing his path. Label the path length of each leg of the journey. Draw the total displacement...

These physics questions are destroying me. I’m not too sure how to
solve vectors and such. Any help would be amazing. But if possible
please explain so I understand. I promise to give 5 stars and
thumbs up if correct.
