At t= 10 s, a particle is moving from left to right with a speed of 5.0 m/s. at t=20 s, the particle is moving right to left with a speed of 8.0 m/s. assuming the particle's acceleration is constant, determine (a) its acceleration,
(b)its initial velocity, and
(c) the instant when its velocity is zero.
