Web26 jun. 2024 · In an orthonormal system, a ball is thrown from a point 𝑃 =(2,6,5) towards a plane with equation 𝑥−𝑧=−2, in such a way that after it bounces off the plane, it passes through the point 𝑄=(3,3,7). What is the ball's direction after the bounce. This question has been posed here before but with a wrong answer. WebThere was a force of gravity. That force of gravity was downward. But what that force of gravity does, it doesn't add or subtract any impulse in the X direction. It tries to add impulse in the downward direction, in the Y direction, so it tries to add vertical component of velocity downward, and so we're not even considering that over here.

WebF can even reverse direction during the bounce. The simplest way to determine how the ball bounces is to film the bounce and then measure what happens from the film. The ratio … Web20 feb. 2009 · So the velocity after the collision is v′ = f w − r u. In a perfectly elastic, frictionless collision, v′ = w − u; that is, the motion is reflected about the normal at the point of collision, as in the diagram given in Bill's answer. This approach works just the same … pitch black game 3d scanner
