A hiker walks 3.70 m, N and 11.58 m, E. What is the magnitude of his resultant displacement?

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

answer; how far out of place which the object finished relative to the starting location;
