A trapper walks a 5.0-lan straight-line distance from her cabin to the lake, as shown in the following figure. Determine the east and north components of her displacement vector. How many more kilometers would she have to walk if she walked along the component displacements? What is her displacement vector?
Check Your Understanding Verify that vector v V obtained in Example 2.14 is indeed a unit vector by computing its magnitude. If the convoy in Example 2.8 was moving across a desert flatland—that is, it the third component of its velocity was zero—what is the unit vector of its direction of motion? Which geographic direction does it represent?
Suppose you walk 18.0 m straight west and then 25.0 m straight north. How far are you from your starting point? What is your displacement vector? What is the direction of your displacement? Assume the +x -axis is horizontal to the right.
The 2010 Soccer World Cup played here in South Africa will always be a history to remember. That was when Simphiwe Tshabalala scored a beautiful long range shot when Bafana Bafana was playing against Mexico in the opening game. After kicking the ball, it touched the goal-line (at ground level) 35.00 m from where he kicked it, and the maximum height reached by the ball was 6.50 m. Use the above information to answer questions 12 to 15. Calculate: 12. Calculate the time at which the ball reached this maximum height. 13. The angle at which Tshabalala kicked the ball relative to the ground. 14. The vertical component of the initial velocity, Voy. 15. The initial velocity at which he kicked the ball.

Sammy the sugar glider is out one morning foraging for fruit. He waddles his body along a tree branch 4.2m at 30degrees EoN and then turns and leaps and glides to a nearby tree that is 6.5m at 15degrees NoW. Using the triangle method, what was his overall displacement?
George runs the football 40 yards downfield before he is tackled. The straight line distance between where he began the run and where he was tackled is 18 yards and makes a 25 degree angle with the right sideline. a. What was George's distance traveled in yards? b. What was George's resultant displacement in yards? PIck answer BELOW a. distance = 58yds, displacement = 18yds b. distance = 40yds, displacement = 22yds c. distance = 40 yds, displacement = 18yds d. distance = 18yds, displacement = 40yds

MY NOTES A small metal ball is kicked from the edge of a cliff. Its x- and y-coordinates as functions of time are given by x = 19.7t and y = 4.20t – 4.90t, wherex and y are in meters and t is in seconds. (Do not include units in your answer.) (a) Write a vector expression for the ball's position as a function of time (in m), using the unit vectors î and j. (Give the answer in terms of t.) By taking derivatives, do the following. (b) Obtain the expression for the velocity vector v as a function of time (in m/s). (Give the answers in terms of t.) m/s (c) Obtain the expression for the acceleration vector a as a function of time (in m/s?). m/s? a (d) Next, use unit-vector notation to write expressions for the position, the velocity, and the acceleration of the metal ball at t = 2.76 s. (Assume the position is in m, the velocity is in m/s and the acceleration is in m/s?.) m/s m/s? a =
