Chapter 1One Dimensional Kinematics1.1 Distance vs. Displacement--Speed vs. VelocityHomework # 01L1x = x - x0v =tL1xv =L1t=x-x0tI1.A squirrel runs 80.0 m along a fence in 6.00 s.The squirrel stops for 2.00 s, then turns around and runs 35.0 m in3.00 s in the opposite direction.a.) What was the distance traveled by the squirrel for the first part of his journey (from 0 to 6.00 seconds)?b.) What was the displacement of the squirrel for the first part of his journey (from 0 to 6.00 seconds)?c.) What was the average speed of the squirrel for the first part of his journey (from 0 to 6.00 seconds)?d.) What was the average velocity of the squirrel for the first part of his journey (from 0 to 6.00 seconds)?e.) What was the distance traveled by the squirrel for the second part of his journey (from 6.00 to 8.00 seconds)?f.) What was the displacement of the squirrel for the second part of his journey (from 6.00 to 8.00 seconds)?g.) What was the average speed of the squirrel for the second part of his journey (from 6.00 to 8.00 seconds)?h.) What was the average velocity of the squirrel for the second part of his journey (from 6.00 to 8.00 seconds)?i.) What was the distance traveled by the squirrel for the third part of his journey (from8.00 to 11.00 seconds)?j.) What was the displacement of the squirrel for the third part of his journey (from8.00 to 11.00 seconds)?k.) What was the average speed of the squirrel for the third part of his journey (from 8.00 to 11.00 seconds)?l.) What was the average velocity of the squirrel for the third part of his journey (from8.00 to 11.00 seconds)?m.)What was the total distance traveled by the squirrel during the entire trip?n.) What was the net displacement for the squirrel for the entire trip?o.) What was the average speed of the squirrel for the entire trip?p.) What was the average velocity of the squirrel for the entire trip?2.How long does it take a car to travel 65.0 m if it is moving at 18.5 m/s?3.A mailman walked in a straight line from one house to another, a distance of 32.5 m, in 12.7 s.What was hisaverage velocity?4.A plane travels from Newark airport to Orlando Florida in 2.25 hours.If the average velocity of the plane duringthis trip was 782 km/h, what was the magnitude of the displacement for the trip?II5.A runner moving through a 5.00 km course takes 21 minutes and 25 seconds to go 2920 m. He wants to finishthe race in 36.0 minutes.What minimum average velocity must he run for the remainder of the course?III6.A runner moving through a 1600 m course takes 5 minutes and 25 seconds to go 1230 m.What must his averagevelocity be for the remainder of the course if his average velocity for the whole race was 3.81 m/s?
