[SOLVED] Net Force Question with no velocity or time given. 1. The problem statement, all variables and given/known data A ball of mass 0.6 kg flies through the air at low speed, so that air resistance is negligible. What is the net force acting on the ball while it is in motion? 2. Relevant equations Fnet = m(change in velocity/change in time) 3. The attempt at a solution Can't attempt because I don't know how to find the change in velocity or the change in time. They don't tell beginning time or ending time, the tell the weight, and neither the velocity. I know the vector will look like <0, y, 0> but I don't know how to calculate the y value.
