<span> y=y0 + vt +1/2gt^2
(solve for t here) cause you know y,y0,v,g
you will do quad formula here
then:
v=v0 +at solve for v
(remember the direction of the ball too (signs))
The main thing to remember here is that when the ball passes exactly (height) where it was launched it will travel the speed at which it was launched. *its almost like the ball was thrown in the downward direction. </span>
Explanation:
According to the law of conservation of mass, the masses at the start and finish of a reaction will stay the same. The law of conservation of mass "mass is always constant in a chemical reaction".
- The law is the basis for chemical calculations.
- Masses of reactants and products must be the same to show that mass is always conserved.
- Disparity in the mass could result from loss of mass to the environment or some side reactions that cannot be easily monitored.

Accelration=changespeed/changetime
changetime=8
changespeed=45-5=40
40/8=5
5m/s^2 is acceleration
Yes, I think that the universe is way to large for there not to be other life forms out there.
