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. p.18 2D-A 2. due east: 0 km I + 4.9 km j 4. 33.00 km, 42.6° south of east 6. Δty=8.9s
