1. The problem statement, all variables and given/known data From t = 0 to t = 5.00 min, a man stands still, and from t = 5.00 min to t = 10.0 min, he walks briskly in a straight line at a constant speed of 1.9 m/s. 2. Relevant equations (a) What is his average velocity vavg in the interval 2.000 min to 7.60 min? ___m/s (b) What is his average acceleration aavg in the interval 2.00 min to 7.60 min? ___m/s2 (c) What is vavg in time 3.00 min to 9.00 min? ___m/s (d) What is aavg in time 3.00 min to 9.00 min? ___m/s2 3. The attempt at a solution a) 1.9*2.6/5.6 = .882 m/s right b) 1.9/5.6/60 = .006 m/s2 wrong c) 1.9*2.6/7 = .707 m/s wrong d) 1.9/6/60 = .005 m/s2 wrong Where did I go wrong?
