1. The problem statement, all variables and given/known data A ball starts from rest and rolls down a hill with uniform acceleration, traveling 150 m during the second 5.0 s of its motion. How far did it roll during the first 5.0 s of motion? Vi= 0 at time t=5s -> d= 150 m 2. Relevant equations d=vf+vi/2 * t 3. The attempt at a solution Vi= 0 since it starts from rest at time t=5s it travels 150 m therefore the final velocity must be 30 m/s plug all of this into an equation d=vf+vi/2 * t= 75 m Total distance= 150m+ 75m= 225m But the answer is wrong. Where did i go wrong?
