be treated independently, they are related by the fact that they occur for exactly the same amount of time, namely the time t the projectile is in the air. What are the values of the initial velocity vector components v 0, x and v 0, y (both in m/s) as well as the acceleration vector components a 0 x and a0, y (both in m/s2)? Here the subscript 0 means "at time t 0." The peak of the trajectory occurs at time t1. This is the point where the ball reaches its maximum height y max. At the peak the ball switches from moving up to moving down, even as it continues to travel horizontally at a constant rate. What are the values of the velocity vector components v 1, x and v 1, y (both in m/s) as well as the acceleration vector components a 1, x and a 1, y (both in m/s2)? Here the subscript 1 means that these are all at time t 1. To understand projectile motion by considering horizontal constant velocity motion and vertical What are the values of the initial velocity vector components v0, x and v 0, y (both in m/s) as well as the acceleration vector components a 0, z and a 0, y (both in m/s2)? Here the subscript 0 means "at time t 0." The peak of the trajectory occurs at time t 1. This is the point where the ball reaches its maximum height y max. At the peak the ball switches from moving up to moving down, even as it continues to travel horizontally at a constant rate. What are the values of the velocity vector components v1, x and (both in m/s) as well as the acceleration vector components a1, x and a1, y (both in m/s2)? Here the subscript 1 means that these are all at time t 1.
Explanation / Answer
at point to, there is both horizontal and vertical velocity. also acceleration is -9.8 so correct answer is , 15,26,0,-9.8 at point t1, (Question C) there is only horizontal velocity. also acceleration is -9.8 so correct answer is , 15,0,0,-9.8
