What is the initial angular momentum of a rigid body given an offset impulsed force?

What is the imparted angular momentum to a rigid body if the impulse force is offset by a distance $h$ from the center of mass and the imparted momentum from the center of mass is $mv$? For a ...

Off-center impulse equations [closed]

A rigid steel bar with mass $M$ is hit sideways (very close to its end) by a steel ball with mass $m$ and velocity $v$. What are the equations of motion after elastic impact and how about conservation ...

Coin inclined at fixed angle toward the horizontal dropped onto table and rebounds [closed]

Here is my question: A circular coin of radius $a$ falls at speed $u$ (without rotating) onto a smooth horizontal table. The perpendicular to its face makes an angle $\theta$ with the vertical. ...

Does inelastic collision say the ball bounces back to you when thrown at an angle on ground?

I created a bounce simulation using exactly the formula from Wikipedia. The behavior I observe is not what I would expect in two cases: When two balls hit off-centre, they act the same as if the ...

Breakdown of velocity components of a pivoting domino rotating 90° clockwise

I'm trying to model/qualitatively analyse the velocity components of a toppling domino about a pivot point, to support the results I procured in my experiment. Essentially I am trying to figure out ...

Mechanics of colliding irregular shapes in 2D or 3D

I am familiar with the mechanics of colliding spheres but I am trying to understand how this generalizes to irregular shapes (eg. 2 cubes colliding in 3D space). Clearly this is a more involved ...

Elastic collision between a point and a rotating solid

Consider a pointwise particle with mass $m_1$ and speed $v_1$, which collides with a solid $S$ of mass $m_2$, rotational inertia matrix $J$, speed $v_2$, and rotational velocity $\omega_2$. I denote ...
