You decide to travel by car for your holiday visits this year. you leave early in the morning to avoid congestion on the roads. this enables you to drive at a comfortable speed of =67.1 mphv1=67.1 mph for =1.70t1=1.70 hours. however, after this time, you unexpectedly come to a stop for =20.0 min. tstop=20.0 min. traffic starts moving again and you finish your travel at =55.8 mphv2=55.8 mph for an additional =1.70t2=1.70 hours. there are 16091609 meters in one mile. what was the total distance traveled?

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
