AI Thread Summary
To calculate the force generated when stopping an object moving towards Earth, the acceleration due to gravity must be considered alongside the object's motion. The initial velocity (vi) is 0.6 m/s, and the final velocity (vf) is 0, with a time (t) of 0.1 seconds. The equation a = (vf - vi) / t can be used to find acceleration, but the net force (f = ma) must account for both gravitational force and the force applied to stop the object. It's important to identify all forces acting on the object, including gravity, to accurately determine the net force. Understanding these components is crucial for a proper calculation.

Hi
I am trying to roughly calculate a force.
If i am moving an object towards the Earth and then stop it, how much force will this generate?
a=vf-vi/t
- vi =0.6m/s
-vf= 0
-t = 0.1 s

This equalling - a

Then applying f=ma
m=150kg

Im unsure how to add gravity into this.

would...
0-(9.8+0.6)/0.1 be a good way to estimate this?

Any help is appreciated.
Thanks in advance[Moderator's note: Moved from a technical forum and thus no template.]

No. The units of grand v are not the same anyway.
Presumably the object is freely falling and you apply an upward force to stop it when it reaches a speed of 0.6 m/s. You want to know that force.
In your equation f = ma, f is actually the net force and consists of more than one force acting on it. Can you identify these forces?

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'

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...
