2D Motion (Optional/Bonus). Kilauea in Hawaii is the world's most continuously active volcano. Suppose a large rock is ejected from the volcano with a speed of 25.0 m/s and at an angle 35.0° above the horizontal, as shown below. The rock strikes the side of the volcano at an altitude 20.0 m lower than its starting point. V-25 m/s L 35 20 m Z
What are the three pieces of information about the motion along x-direction, such as the initial and final speed and acceleration along x-direction? What are the three pieces of information about the motion along y-direction, such as the initial velocity, acceleration and final displacement along y-direction?
Calculate the time it takes the rock to follow this path. Remember the time is determined by the motion along vertical (y) direction, and you will need the quadratic formula: t = (-b+/-sqrt(b^2-4ac)/(2a).
Calculate the range of the rock (the distance along x-direction).
What are the x- and y-component of the velocity when the rock hits the ground?
