Question

Use the POSITION vs. TIME graph below to answer the following questions. Let south be the positive direction & let north be the negative direction. Express all answers in the appropriate mks units.

A.) Determine the magnitude & direction of the velocity at 0.3 s. ?

B.) Determine the magnitude & direction of the velocity at 1.7 s. ?

C.) Determine the total distance traveled. ?

D.) Determine the magnitude & direction of the total displacement. ?

E.) Determine the average speed. ?

F.) Determine the magnitude & direction of the average velocity. ?

Explanation / Answer

a) magnitude is approx -0.7 and direction is south b) magnitude is approx 1.3 and direction is north c) Total distance is 12m d) displacement = 3m e) Avg speed is s/t= 12/5= 2.4m/s e) avg velocity is 0.6m/s and its direction is towards north
