Hi guys, can you help me out with these 2 multiple choicequestions and provide and brief explanation for the answers youhave chosen please. Thanks again! It's much appreciated! 1. Ax is the __________ vector of a. magnitude.
b. x-component c. direction
d. size e. displacement

Explanation / Answer

A vector is made up of two components, an x component and a ycomponent. Thus, Ax is the x component of the vector A. That's howwe identify at x and y of a vector. If it was vector R, thecomponents are Rx and Ry. The acceleration vector of a particle in projectile motion isdirected down at all times. The acceleration is the accelerationdue to gravity, and in a projectile motion, it is always pointeddown and remains constant. Thus, the equation in the verticledirection Fy would be Fy=ma, where "a" is the acceleration due togravity valued at 9.81m/s2 and the "m" is the mass ofthe object. Martha
