Hop height of a rod and speed/ time if hit upward with force f

AI Thread Summary
The discussion focuses on the dynamics of a rod's motion when struck upward with a force. It emphasizes that force is not the appropriate metric for analyzing the situation. Instead, modeling the interaction as an elastic collision between the rod and hammer is suggested. The final velocity of the rod will be influenced by the mass and initial velocity of the hammer. Additionally, the force during the collision varies over time and is affected by the material properties of both the rod and hammer.

Homework Statement
Ok if I hit a steel rod with a mass of m with a force of f how high will it jump up. how fast will it go? This is one hit like a hammer hitting a rod or ball in the air. If there is a computer program that will do this math that would be better.
Relevant Equations
I don't know it
I want to make a few of these if it will not cost a lot.

Force is not the right unit to look at. You can model the collision as approximately elastic collision of rod and hammer, the final velocity of the rod will depend on the mass and initial velocity of the hammer.

The force during the collision will change over time and depend on material properties of rod and hammer you don't want to deal with.
 
Thread 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'
Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
