The purpose of the two studies presented in this paper is to establish validity evidence for the Sport Multidimensional Perfectionism Scale-2 (Sport-MPS-2: Gotwals & Dunn, 2009). Studies 1 and 2 are respectively focused on the production of structurally-related and external validity evidence.
The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
First you want to find the angle between each initial velocity vector and the horizontal axis. This is your angle (theta). The speed given is the magnitude of velocity. Be sure to keep your magnitudes and angles organized.Calculate the x and y components of the individual velocity vectors.The x component of a vector is parallel to the horizontal axis of a graph. The y component is parallel to the vertical axis.
