Physics help based on dropping/throwing up objects??

Question

Well theres a problem i need help with. It says some one throws the object up in the air and they give you an initial speed im pretty sure. They want to find out what the maximum distance it will reach before the object falls. I was obviously paying attention about dropping objects, but how do you do this one?

Answer 1

It's just like falling in reverse:

x = (V^2)/2a

Use the initial speed for V and g for a

This is a good formula to use when you don't know the time invloved.......

Answer 2

Quantum mechanics isn't precisely "diverse physics". It reduces to classical mechanics under the shrink of limitless mass, so classical mechanics may be considered as a undeniable shrink of quantum mechanics, not a thoroughly separate element. Astronomical gadgets are sufficiently huge which you prefer standard relativity (and doubtless even D-brane cosmology) to describe their habit, so in a fashion they are already consistent with a diverse theory. yet there's no theoretical reason to think of that the version between the habit of a bowling ball and an astronomical merchandise is as huge by way of fact the version between the habit of a sub-atomic particle and a bowling ball. according to probability a reason will arise sooner or later, i don't comprehend.

Answer 3

use the equation:vsq.=usq.+2as. v=the velocity at max height which will be 0. u=the velocity that the object was thrown with . a=acceleration due to gravity (-9.8)which is -ve since this is based on free fall and s=the height.all u got to do now is transpose for s.

Answer 4

x=final position
x0=initial position
v=velocity
v0=initial velocity
a=acceleration
t=time

(delta x)=(v0)(t)+(1/2)(a)(t^2)

v=v0+at

v^2=v0^2+2(a)(delta x)

these kinematic equations are useful in most projectile motion problems.

Answer 5

Basic dynamics equation.
