Xavier starts 5 feet away from a motion detector. He then walks away from the detector at a rate of 0.5 ft/sec for 4 seconds. He remains still for 2 seconds and then walks toward the detector at a rate of −2 ft/sec for 3 seconds. How far in feet is Xavier from the motion detector when he finishes his walk?

The Shinkansen (bullet train in Japan) makes a trip from Tokyo Station to Kyoto station in 2.0 hours and 14 min. The distance traveled is 460 km (to two significant figures). Determine the average velocity of the train in meters per second (m/s). [conversions: 1 km = 1000 m, 1 hr = 3600 s, 1 min = 60 s] *Round your answer to two significant figures in the standard form* *
Hi I am in physics 1 and I need help with this problem. It saids a boy runs in an open field. He runs 233m due north in 77 seconds, turns 90 degrees to his left and runs 178m in 93 seconds. Sketch a map of his motion and find the following quantities of his motion during this period from starting time to final time a) Map of his motion b) The total distance he runs (233m + 178m= 411m) c) The displacement from starting position to final position. What I have thus far is I got c=sqrt (233)^2+(178)^2=293m. Would I subtract this number from the total distance? Please includes detailed steps of how to solve this

A turtle crawls along a straight line, which we will call the xx-axis with the positive direction to the right. The equation for the turtle's position as a function of time is x(t)=50.0cm+(2.00cm/s)t−(0.0625cm/s2)t2x(t)=50.0cm+(2.00cm/s)t−(0.0625cm/s2)t2. At what time tt is the turtle first time a distance of 10.0 cm from its starting point?
A pilot flies in a straight path for 1 hour 45 minutes. She then makes a course correction, heading 30 degrees to the right of her original course, and flies 2 hours 30 minutes in the new direction. If she maintains a constant speed of 340 mi/h, how far is she from her starting position? Give your answer to the nearest mile.
