42-It is not 42, idk what that is, it's -16t^2+vt+s, now that is the RIGHT answer!
vf=vi+at or vf2=vi2+2ad where a=-9.8m/s2
what is the formula for a vertical angle
The formula for velocity is (v = d/t) or (velocity = distance/time).
The horizontal velocity has no bearing on the time it takes for the ball to fall to the floor and, ignoring the effects of air resistance, will not change throughout the ball's fall, so you know Vx. The vertical velocity right before impact is easily calculated using the standard formula: d - d0 = V0t + [1/2]at2. For this problem, let's assume the floor represents zero height, so the initial height, d0, is 2. Further, substitute -g for a and assume an initial vertical velocity of zero, which changes our equation to 0 - 2 = 0t - [1/2]gt2. Now, solve for t. That gives you the time it takes for the ball to hit the floor. If you divide the distance traveled by that time, you know the average vertical velocity of the ball. Double that, and you have the final vertical velocity! (Do you know why?) Now do the vector addition of the vertical velocity and the horizontal velocity. Remember, the vertical velocity is negative!
Velocity is distance / time
vf=vi+at or vf2=vi2+2ad where a=-9.8m/s2
'Vertical velocity' means speed up or down.
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
Vertical Velocity - roller coaster - was created in 2001.

what is the formula for a vertical angle
v2=sqrt(2*g*h) v...starting velocity g...gravity h...height achieved
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.
Note - the vertical velocity is zero ... there may be considerable horizontal velocity. And vertical velocity is zero because the object is going neither up nor down.
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 formula for velocity is (v = d/t) or (velocity = distance/time).
