1. The problem statement, all variables and given/known data The force on a particle of mass 3.0 kg moving in one dimension at time t, is given by: F = 9.0 +2.0t - 4.0t2. What is the velocity of the particle? (Let v0=0 and ti=0) 2. Relevant equations I know to use F = ma for sure. And I believe this is the motion equation I should be using, but I'm not completely sure: v = v0 + at 3. The attempt at a solution I substituted in the given equation for F and the given mass into Newton's 2nd Law equation and solved for the acceleration. I then further substituted in acceleration into the velocity equation and let v0 = 0 and t = 0, which just appeared to make the velocity 0 m/s which doesn't seem correct. Could someone point me in the correct direction?
