1. The problem statement, all variables and given/known data A ball is falling freely under the action of gravity. When its downward speed is 8m/s, it explodes into two equal parts. One part goes straight up to a height of 12m above the explosion point. What is the velocity of the other part just after the explosion? 2. Relevant equations initial = final P1 +P2 = P1 + P2 3. The attempt at a solution i know that the other piece goes with a force downwards iam not sure how to start this i figure the straight line motion equation s= ut +1/2 at(squared) could be used? when the object reaches 12 meters, the velocity would be 0 as gravity would be decelerating it.
