2D to 3D video conversion (also called 2D to stereo 3D conversion and stereo conversion) is the process of transforming 2D ("flat") film to 3D form, which in almost all cases is stereo, so it is the process of creating imagery for each eye from one 2D image.

    How Is Time Calculated for Angle Reduction in Javelin Throw Projectile Motion?

    4.In the javelin throw at a track-and-field event, the javelin is launched at a speed of 30 m/s at an angle of 33° above the horizontal. As the javelin travels upward, its velocity points above the horizontal at an angle that decreases as time passes. How much time is required for the angle to...

    Determining angle and ratio in 2d motion

    When baseball outfielders throw the ball, they usually allow it to take one bounce on the theory that the ball arrives sooner this way. Suppose that after the bounce the ball rebounds at the same angle as it had when released (Fig. P3.70) but loses half its speed. (a) Assuming the ball is...

    Calculating Acceleration at t = 2.20 s for a Particle in 2D Motion

    At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of vi = (3.00 i - 2.00 j) m/s and is at the origin. At t = 2.20 s, the particle's velocity is v = (9.20 i + 6.10 j) m/s. i am asked to find the acceleration at time t. i know that the acceleration is the...

    Solve 2D Motion Problem: Ball Hitting Canyon Edge

    Ok, in this problem a ball with velocity 10m/s flys off the horizontal edge of a canyon, the equation for the canyon is y^2=16x and it wants you to find the x,y cordinates where the ball hits it. I turned the balls motion into a a function of x for y and then set that equal to y=Sqrt(16x) but I...
