Question

define velocity of projection

Answer 1

velocity in a projectile motion can be divide into two.that is the vertical velocity and the horizontal vilocity.the horizontal vilocity remains always constant as according to equations of motion fo the x component the enitail velocity is equal to the final vilocity.talking about the vertical vilocity,at higghest point it is 0 and so we can say the vilocity is purely horiontal at the highest point.to calculate vilocity we dezvide it into x and y component i.e. ucosФ and usinФ. 

Answer 2

Answer:

VELOCITY:

            The velocity is defined as the rate of change of displacement of an object in the particular time taken.

                               Velocity(V) $=\frac{Displacement}{Time taken}$

The S.I. unit of velocity is m/s.

VELOCITY OF PROJECTION:

    The velocity in which the object is projected or the speed and time difference in which the object is projected it is called projectile velocity.

The projectile velocity is depended on various factors like flight, range, etc.

The formula to determine the projectile velocity is,

Horizontal velocity component:

                         $V_{x}=Vcos(\alpha )$

Vertical velocity component:

                     $V_{Y}=Vsin\alpha$

The total velocity in projectile motoin is,

                   $V^{2}=V_{x}2} +V_{y} {2}$
