The total horizontal distance traveled by a bouncing ball nudged off a table of height $H$ [closed]
Suppose a ball gently rolls off a flat surface of height $H$ and free falls to the ground subject only to the law of gravity. Once the ball hits the ground, it rebounds as shown in the figure. When ...

For an objective falling, reaching terminal velocity and then hitting the ground, how can I find the force it exerts on the ground? [closed]
For example object with v=tanh(0.1213)t/0.01236. m=69kg.
I thought I had to use F=mv/t but that just gives the net force of the object while falling.
I don't know how to find the force impacting on ...

Extra force in other frame paradox
Suppose there are two balls: one steel ball that cannot break with a mass of 10 kg, and another smaller wooden ball with a mass of 1 kg, which will break if a force of 10 N is applied to it.
Consider ...

After how many bounces will a ball's mechanical energy equal zero?
This was a question I asked myself for fun. It turned out to be more difficult than I initially imagined.
The Problem: Let's say a ball is dropped from h0. Air friction is negligible. The collisions ...

Ball colliding with inclined stationary plane
A particle with mass m1 is dropped from a height onto an incline plane creating the angle $\alpha$ with the ground (the slope is frictionless). The coefficient of restitution is e. Find the angle $\...

Elastic collision between 2 particles in 2D [closed]
A particle with mass $m_1=m$ moves along the x-axis at a velocity of $v_0$ and collides with another particle $m_2=4m$. As a result of the collision $m_1$ travels upwards at an angle of $90 ^\circ$. (...

Ball collisions
When two balls collide directly, the impulse of the collision acts along the line of centers, so the momentum along this direction is not conserved. Therefore, I can only use the conservation of ...

Conservation of Kinetic energy in splitting
If a stationary mass $M$ explodes into 2 masses $m_1$ and $m_2$ with velocity $v_1 $and $v_2$ respectively releasing no energy in any other form like sound and heat.
Then I've read that-
intial k.E = ...

Fully ellastic collision of 2d ellipses
I want to describe the behavior of two identical 2d ellipses with mass $m$ (rigid bodies), parametrized by $\phi_{a,b}(\alpha)=(a\cos(\alpha),b\sin(\alpha))$, after a fully ellastic collision without ...

Does this question require any calculus to solve? [closed]
So, I came across this question in a book,
Two spherical bodies of mass $M$ and $5M$ and radii $R$ and $2R$, respectively are released in free space with initial separation between their centers ...
