  7. KAP #10 adding vectors • The pronghorn antelope, found in North America, is the best long-distance running among mammals. It has been observed to travel at an average speed of more than 55 km/hr for up to 6.0 km. Suppose the antelope runs a distance of 5.0 km in a direction 11.5 degrees north of east, turns, and then runs 1.0 km south. Calculate the resultant displacement. • In 1926, Gertrude Ederle of the United States became the first woman to swim across the English channel. Suppose Ederle swam 25.2 km east from the coast near Dover, England, then made a 90 degree turn and traveled south for 21.3 km to a point east of Calais, France. What was Ederle’s resultant displacement? • A killer whale can swim as fast as 15 m/s. Suppose a killer whale swims in one direction at this speed for 8.0 s, makes a 90 degree turn, and continues swimming in the new direction with the same speed as before. After a certain time interval, the magnitude of the resultant displacement is 180.0 m. Calculate the amount of time the whale swims after changing direction.

  12. KAP #11 • The longest snake ever found was a python that was 10.0 m long. Suppose a coordinate system large enough to measure the pythoon’s length is drawn on the ground. The snake’s tail is then placed at the origin and the snakes body is stretched so that it makes an angle of 60.0° with the positive x-axis. Find the xa and y coordinates of the snake’s head. • The landing speed of the space shuttle Columbia is 347 km/h. If the shuttle is landing at an angle of 15.0° with respect to the horizontal, what are the horizontal and vertical components of its velocity?

  13. KAP #12 • A car parachutes down from a plane 1000 m in the air at a constant speed of 15 m/s. The wind is blowing at 3 m/s to the west. • How long will it take to hit the ground? • What is the resultant velocity of the car? • What angle off of the vertical is the car moving? • What is the total distance that it will travel while in the air? • What is the horizontal displacement of the car from the point it left the plane to the point it landed?
