This is going to give us nine point four meters per second there's gonna be our VX.
vertical componentWhen a projectile reaches maximum height, the vertical component of its velocity is momentarily zero (vy = 0 m/s). However, the horizontal component of its velocity is not zero.
The convention is that left is negative for the horizontal direction, x, and down is negative for the vertical direction, y.
The trajectory of a projectile depends on motion in two dimensions. The x component is the horizontal motion of the projectile, and the y component is the vertical motion of the projectile. The units to express the horizontal and vertical distances are meters (m).
vertical portionThe vertical portion of its velocity is briefly zero as a projectile hits a high.
vertical componentMaximum Height, H: The maximum height of a object in a projectile trajectory occurs when the vertical component of velocity, vy , equals zero.

Then X is going to be equal to five point two kilometers multiplied byMoreFive point two kilometers. Then X is going to be equal to five point two kilometers multiplied by the sine of sixty-two degrees and that turns out to be four point six kilometers.
The horizontal velocity component (vx) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (vy) describes the influence of the velocity in displacing the projectile vertically.
Yes, an object can have zero velocity and still be accelerating simultaneously.
The vertical component of the ball's velocity at its maximum height equals zero. The vertical component of the ball's acceleration at its maximum height is a y = − g a_y=-g ay=−g .

And in blue you see this constant horizontal velocity a projectile is a simultaneous mix of these two independent motions.
The final vertical velocity of a projectile is always equal to the initial vertical velocity. The vertical acceleration of a projectile is 0 m/s/s when it is at the peak of its trajectory.
