question 73

Multiple Choice

A particle moves from an initial position with coordinates x = +7.0 m,y = +2.0 m,to an intermediate position with coordinates x = +4.0 m,y = +5.0 m in a time interval of 3.0 s.The particle then moves from the intermediate position with coordinates x = +4.0 m,y = +5.0 m,to a final position with coordinates x = +1.0 m,y = +8.0 m in a time interval of 6 s.What is the magnitude of the average velocity for the total displacement?

• A)0.94 m/s
• B)1.1 m/s
• C)1.3 m/s
• D)2.1 m/s
• E)3.0 m/s
