Ball Bouncing on an Inclined Plane: Force and Velocity Analysis

  • Start date Start date
AI Thread Summary
The discussion focuses on analyzing the forces and velocities involved when a ball is dropped from a height and strikes an inclined plane. The user seeks to determine the force exerted on the ball upon impact and its velocity after bouncing off the surface. Initial calculations include the velocity formula V=(2gh)^0.5 and momentum p=mV, leading to considerations of gravitational force and its components on the inclined plane. The user expresses uncertainty about the calculations and invites further questions for clarification. The thread emphasizes the importance of understanding the dynamics of motion and force interactions in this scenario.

Hello, my problem:

A ball (assume its a point) is dropped from height h without initial speed, after some time of falling it will hit an inclined plane (at angle alpha to normal) and bounce off (see the pretty picture, i think it explains alot).

Question 1: What is the force F?
Question 2: What is the velocity after the bounce?

Started with:
V=(2gh)-1

Ek=(mV2)/2

p=mV => p=m(2gh)-1

F=ma

Q=mg (weight)

My brainstorming yielded this:
Qn=Qcos(alpha)
Fq=Fcos(alpha)

*what is marked as -Fn in the picture* = -(Fn+Qn)

I hope that is it, but I can be forgetful at times. So if you have questions... shoot!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
