when something is at its Max height (projectile motion), what is the direction of it's velocity?
I know the velocity will be the velocity of the x component (since the y component would be 0), but I'm not sure how to find the angle.

47. An object undergoing projectile motion travels 1.00 x 102 m in the horizontal direction before returning to its initial height. If the object is thrown initially at a 30.0° angle from the horizontal, determine the x component and the y component of the initial velocity. (Neglect any effects due to air resistance.) Example 3-7

Relative Velocity and Projectile Motion . a)An airplane moves horizontally with a constant velocity VA/G 300m/s with respect to ground at height H = 600m. The plane fires a container, which has a speed VC/A = 300m/s and direction α = 300 with respect to the airplane immediately after the firing. The container performs a projectile motion and hits the ground at a horizontal distance L from the point of the firing (see figure a)What is the velocity (horizontal and...

A projectile is launched from the top of a 75m-tall cliff with an initial velocity of 31m/s at an angle of 42° above the horizontal. For this problem, assume that the base of the cliff is at y 0 and that the projectile starts at x 0 on a standard xy plane 1. What is the maximum height above the ground that the projectile will achieve? 2. How long will it take for the projectile to reach its maximum height?...

If the projectile is launched at a launching angle theta, with
an initial velocity Vo from a height of Yo above the table top, how
long does it take the projectile to fall on the table top? Now that
your Voy is no longer zero, so you must use the quadratic equation
to solve for t. Express the time in terms of g,Yo,Vo, and theta,
make sure that your y-direction is fixed.
