The rocks are launched in the directions indicated above. rock x is thrown vertically downward, rock y is thrown vertically upward, and rock z is thrown horizontally. The projectiles do not land on the same terrain, however. Which of the following correctly relates the magnitude vy of the vertical component of the velocity of each rock immediately before it Rocks 1 and 2 have identical initial vertical velocities and are affected by gravity equally, while Rock 3 starts with no vertical component. Three projectiles (A, B, and C) are launched with different initial speeds and angles. 20. A rock is dropped off a cliff and strikes the ground with an impact velocity of 30 m/s. describe the motions of the three balls, and compare the speeds of the balls as they reach the ground. Note: when analyzing phenomena using the Energy-Interaction Model, only the initial and final indicators Three identical cannonballs are launched with the same initial speed but at different angles, as shown in the figure. The rock falls through a vertical distance of 1. Another projectile is fired from the surface of planet B with a velocity of 6 m / s at the same angle follows trajectory which is identical with the trajectory of projectile from planet A. 28 terms. 00 kg. The first ball is thrown horizontally, the second is thrown at some angle above the horizontal, and the third is thrown at some angle below VIDEO ANSWER: The direction and the sign of work are related to this question.
