Want this question answered?
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
when a body is thrown at an angle in a projectile motion, the vertical component of the velocity is vcos(B) ..where v is the velocity at which the body is thrown and B represents the angle at which it is thrown.Similarly horizontal component is vsin(B). these components are useful in determining the range of the projectile ,the maximum height reached,time of ascent,time of descent etc.,
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case).

no.
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
The initial velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).
The vertical velocity is zero at the highest point. It has ceased moving upward and will begin moving downward. Gravity and air resistance will have negated the original vertical velocity (y-component). So the velocity at the highest point has only a horizontal or x-component.

Gravity... I think
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
when the vertical component of its velocity is zero.
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.
The 'x' component of the velocity is usually the label given to the horizontalcomponent. Also, remember, we generally ignore air-resistance in this typeof exercise. When we do that, there is no horizontal force on the object, sothe horizontal component of velocity can't change.The only force on the object is gravity, and that's completely vertical, so onlythe vertical component of velocity can change.
