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 6.8 m/s. Assuming the particle's acceleration is constant, determine the following. (Assume the positive direction is to the right.) (a) its acceleration (Enter your answer in m/s2. Indicate the direction with the sign of your answer.) (b) its initial velocity (Enter your answer in m/s. Indicate the direction with the sign of your answer.) (c) the instant (in s) when its velocity is zero
