ok the question is...A ball is thrown upward at time t= 0 seconds with an initialvelocity of Vi=12 m/s. How long does the ball stay in theair? please, i really need help on this, i dont under stand whichformula to use to get the answer, and ive tried may times. ok the question is...

Explanation / Answer
This is only dealing with the force of gravity along with yourinitial velocity. Because you need to solve for time, begin byusing the equation velocity as a function of time: V=V1+at V is your final velocity, V1 is your initial velocity, a is youracceleration due to gravity and t is the time period. You aretrying to find out how long it takes for the ball to hit theground, at which point your velocity will be zero. The equation should look like this: 0=12+(-9.8)*t -12=-9.8t t=1.224 seconds
