A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69
A student at the top of a building of height h throws one ball upward with a speed of vi and then throws a second ball downward with the same initial speed vi. Just before it reaches the ground, is the final speed of the ball thrown upward (a) larger, (b) smaller, or (c) the same in magnitude, compared with the final speed of the ball thrown downward?

A particle starts from the origin of a three-dimensional coordinate system and undergoes two consecutive displacements: r 1 → = 2.0 m i ^ + 1.0 m j ^ + 3.0 m k ^ r 2 → = − 1.0 m i ^ − 3.0 m j ^ − 1.0 m k ^ What is the distance of the particle from the origin after these two displacements?
Question 3. Siblings Alice and Bob saved their money all summer to buy a water balloon launcher, and they are eager to take it for a test run. Younger brother Bob thinks he's a pretty fast runner with a top speed of 5 m/s. Не poses the following challenge to his sister: "I'll stand 20 m from you and I'll start running away as soon as you launch a water balloon. See if you can hit me!" Unfortunately for Bob, Alice is a physics 8A ace and knows exactly what needs to be done to soak her brother. (a) Set the origin of your coordinate system at Alice's position with Bob starting along the positive x-axis (and running along the x-axis). Assuming Bob runs at a constant velocity, what is Bob's trajectory rB(t)? (b) Suppose the water balloon launcher is limited to only firing at an angle of T/4. In terms of the unknown initial launch speed v, what is the trajectory of the water balloon rwB(t)? (c) What speed v should Alice launch with to ensure a direct hit? (d) How long does the balloon take…
