The Centre of mass of an exploding projectile

AI Thread Summary
The discussion centers on the behavior of the center of mass of an exploding projectile. It is established that the center of mass follows a parabolic path, similar to that of the intact projectile. The introduction of broken masses with vertical velocity components does not alter this trajectory. Participants emphasize that all fragments must eventually have a vertical component as they fall. The consensus is that the center of mass's path remains unchanged despite the explosion.

I know that the centre of mass moves in the path (the parabola) that the intact projectile would have followed but does the answer change if the new (broken) masses also have a vertical component of velocity?

If ? How could they NOT have a vertical component? What does a parabola look like? Do you think that something traveling in a parabola has no vertical component?

That shouldn't change the answer. If you think about it, the new masses must have a vertical component of velocity at some time ( since they have to fall down).
EDIT: I see your question had already been answered by phinds !
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
