Question

To visit your favorite ice cream shop, you must travel 480 m west on Main Street and then 980 m south on Division Street. Suppose you take 45 s to complete the 480-m displacement and 76 s to complete the 980-m displacement PartA What is the magnitude of your average velocity during this 121-second period of time? Express your answer to two significant figures and include appropriate units. alueUnits Submit Part B What is the direction of your average velocity during this 121-second period of time? Express your answer to two significant figures. o south of west Subnit Request Answer

Explanation / Answer

A) average velocity = total displacemnt/total time taken

= sqrt(480^2 + 980^2)/121

= 9.02 m/s

B) direction of average velocity,

theta = tan^-1(980/480)

= 63.9 degrees south of West

C) Average speed = total distance/total time taken

= (980 + 480)/121

= 12.1 m/s
