Particle Acceleration (Posted on 2004-05-06) Difficulty: 2 of 5
A particle is travelling from point A to point B. These two points are separated by distance D. Assume that the initial velocity of the particle is zero.

Given that the particle never increases its acceleration along its journey, and that the particle arrives at point B with speed V, what is the longest time that the particle can take to arrive at B?

zero velocity does not mean zero acceleration, as has already been pointed out.

If you throw a ball straight up, then it's acceleration (once it leaves your hand) is "-g" (in a downward direction).  At some point, it reaches it's peak and it's velocity is briefly zero, yet the acceleration is still a constant -g
