**Projectile Motion in Two Dimensions****Explanation:**A boy tosses a ball into the air so it follows a 2-D parabolic curve in the x and y directions, as shown in the drawing below. The curve demonstrates the typical trajectory of a projectile under the influence of gravity, with an initial velocity given by \( v_0 \).**Diagram Explanation:**- The diagram is labeled with an x-y coordinate system to represent the horizontal (x) and vertical (y) components of the ball's motion.- The trajectory of the ball is depicted as a dotted parabolic curve starting from the origin point, moving upwards, reaching a peak, and then descending back towards the ground.- Points A, B, C, and D are marked along the trajectory to illustrate different positions of the ball.**Points on the Trajectory:**- **Point A:** The initial point where the ball is tossed with an initial velocity \( v_0 \).- **Point B:** A point located near the peak of the curve.- **Point C:** A point located on the descending part of the trajectory.- **Point D:** The final point where the ball lands back on the ground.Using this figure, identify at which of the points the ball's vertical velocity component is zero. For a projectile, the vertical velocity component momentarily becomes zero at the highest point of its trajectory. Hence, at point B, the ball’s vertical velocity component is zero.

Peter throws a baseball through a houses window. He stands 3.4 m from the window. The ball starts in his hand 1.1m above the ground and goes through the window at a point 2.4 m off the ground. a. Sketch the problem, including an xy coordinate system with the origin on the ground directly below the initial position of the ball, the y axis pointing upward, and the x axis pointing toward the house. b. What are the initial and final coordinates of the ball?
A The spiral is an example of a mathematical form appearing in nature, from the visible construction of seashells, pinecones, and galaxies to the movement behavior of certain animals. The position of a hungry animal that moves outward along a spiral path, searching for food, can be written as r(t)=Atcos(t)i+Atsin(t)j. Write an expression for the velocity of the animal in component form.
You are watching a friend practice archery when he misses the target completely, and the arrow sticks into the ground. Discouraged, your friend asks whether you can help by estimating the speed with which the arrow left the bow. Remembering your physics class, you realize that you can do so by measuring its height above the ground when it was launched, if you assume the arrow was launched horizontally and that the ground is level. For your analysis, you let h represent the arrows height above the ground when it was launched, v0 represent the launch speed, and represent the angle the arrow makes with the horizontal when it is stuck into the ground. Find an expression for v0 in terms of h and .
Figure P4.8 shows the motion diagram of two balls, one on the left and one on the right. Each ball starts at a point labeled i. The ball on the left is released and falls straight down. At the same time, the ball on the right is launched horizontally and follows the path shown. a. Use the given coordinate system to write the position of points i, C, E, G, and K in component form for each ball. b. Find the displacement of each ball from i to points C, E, G, and K. c. Compare your answers for the two balls in part (b). What similarities do you notice? FIGURE P4.8 Problems 8 and 26.

Now we want to figure out how fast the boulder needs to be going horizontally in order to get all the way to the target in that amount of time. Let's say the target is 45 cm away. How fast does the boulder need to be going to get that distance in 0.43 seconds? * This is the speed at which your boulder needs to be launched. The "launch speed" !
