Document Summary
1000 m 63 m 197 m/s x t x. Evaluate: for the first 1. 15 s of the flight, average velocity depends on the time interval chosen. The average velocity is zero. (b) for the round trip, Evaluate: the average velocity for the trip from the nest to the release point is positive. Identify: target variable is the time average velocity to the displacement and average time. And x t so x v av-x v av-x x t v x av- t it takes to make the trip in heavy traffic. Execute: use the information given for normal driving conditions to calculate the distance between the two cities: Now use av-xv v x av- x t for heavy traffic to calculate x v x av- t (105 km/h)(1 h/60 min)(140 min) 245 km. The trip takes an additional 1 hour and 10 minutes. Evaluate: the time is inversely proportional to the average speed, so the time in traffic is (105/70)(140 m)
