V_(x) and V_(y) are the horizontal and vertical compounds of velocity with x and y as the corresponding displacements along horizontal and vertical at any time t in a projectile motion in XY co-ordinate system, where g is the acceleration due to gravity.

V_(x) and V_(y) are the horizontal and vertical compounds of velocity

1.	V_(x) and V_(y) are the horizontal and vertical compounds of velocity with x and y as the corresponding displacements along horizontal and vertical at any time t in a projectile motion in XY co-ordinate system, where g is the acceleration due to gravity.
Answer» SOLUTION :In projectile motion HORIZONTAL component of velocity remains constant. Hence tis will be straight line II to time AXIS. y-t GRAPH is PARABOLIC.
