One afternoon, a couple hikes 70.0 % of the way around a circular lake, the radius of which is 2.50 km . They start at the west side of the lake and head due south to begin their hike. What is the displacement for the couple's hiking trip? Give your answer as an ordered palr, with magnitude first, followed by a comma, then followed by the direction. Give the direction in terms of an angle measured CCW from the Easterly direction. View Available Hint(s) IGAZO + O 2 ? magnitude, direction = krn, degrees CCW from East Submit Previous Answers Part C If the couple makes the trip in 3.2 hours, what is their average velocity for the trip? Give the magnitude of their average velocity. V AXPO 2 ? km/h Submit Request Answer Part D Assume that the couple walks at a constant speed for the entire duration of their hiking trip. Consider two instants in their trip, with the first instant being when the couple was at the Southernmost point in their trip, and the second instant being when the couple was at the Easternmost point in their trip. What was the change in velocity of the couple between these two instants in time? Give your answer as an ordered pair, with magnitude first, followed by a comma, then followed by the direction. Give the direction in terms of an angle measured CCW from the Easterly direction. View Available Hint(s) VALOR O ? magnitude, direction = km/h, degrees Submit Part E At the end of their hike, the couple catches a shuttle bus back to their starting point, where they have left their car. What is the direction of the displacement for their bus trip? Give the direction in terms of an angle measured CCW from the Easterly direction. Give the direction in terms of an angle measured CCW from the Easterly direction.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
