What is the average velocity (in m/s) in x direction between times 1.45 s and 2.2 s (sign matters!) ? Provide your answer with 2 decimal places, don't use scientific notation. Your Answer: Answer 13 8 14 Quiz Information A Question 14 (2 points) Retake question A jogger starts at position x = 0 m, y = 0 m. They first jog along the vector described by 39m 1 + 11m in 62 seconds. Then they jog along the vector described by -10m + 46m in 87 seconds, and finally along the vector described by -13m - 46mj in 86 seconds. What is the average velocity of the jogger (in m/s to 2 decimal places, don't use scientific notation)? Your Answer: Answer MacBook Pro
