5. A sport car (S) is traveling west at 110 km/h. At an intersection 25 km ahead, a truck
(T) is traveling north at 75 km/h. (i) Write the position vector of the truck relative to
the sport car rsr in terms of the unit vectors i and Ĵ. (ii) How long after this moment
will the sport car and the truck be closest to each other? (iii) How far apart will they be
at that point?

Goro Shigeno (Pitcher) and Joe Gibson Jr. (hitter) went head to head in the Major League Baseball (MLB) series. For the last pitch, Gibson hits the baseball with 82 ft/s at angle of 75°. When the ball is directly above Shigeno he begins to run under it. Determine the (a) the total distance that the pitcher runs and (b) the constant speed at which pitcher must run in order to make the catch at the same elevation at which the ball was hit. (Note: the distance between the pitcher and hitter is 70 ft.)
An ant undergoes three successive displacements: ?⃗1=3.00 m,20.0 degrees south of east ?⃗2=2.00 m,north ?⃗3=7.00 m,35.0 degrees west of south a) Carefully sketch and label the three displacements with their tails at the origin. Use a coordinate system in which the positive x-axis is east and the positive y-axis is north. b) Calculate the x-and y-components of each of the displacements. c) Use the results of part b) to calculate the distance between where the ant begins and where it ends. d) What fourth displacement (magnitude and direction) is necessary to return the ant to its initial position?

Susan is an airline pilot flying from one city to another city 1357 km away due east. Her airplane is capable of flying 590 km/h in still air. In the absence of wind, she would simply aim her airplane due east and arrive at her destination 2.30 h later (a very simple Chapter 2 question). Unfortunately for her (and for you), there is a cross-wind (due north or due south -- you need to figure out which direction) which remains constant througout her trip. To account for the wind, she aims the airplane in the direction 27.0° south of east. City #1 City #2 Draw a vector diagram showing how the velocities of the plane relative to the air (õpA), а. plane relative to the ground (õpg), and air relative to the ground (VAG) are related to one another. The following should be obvious from your diagram: (1) the direction of each velocity vector, and (2) which two velocities add up to the third. b. Calculate the wind speed. C. How long does it take for Susan to reach her destination?
