    Can we use conservation of energy law to find final velocity

    Homework Statement It's a simple problem, you kick a ball with an initial velocity of 5.4 m/s, the angle is 30 degrees. So the question is when does it land on the ground? So I thought that I could find final velocity so that I can use V = V(initial) + acceleration * time. My question is, can...
