The figure gives the acceleration a versus time t for a particle
moving along an x axis. The a-axis scale is set by as = 16.0 m/s2.
At t = -2.0 s, the particle's velocity is 8.00 m/s. What is its
velocity at t = 6.0 s? A graph has a vertical axis labeled a sub s
and a horizontal axis labeled t of s. The variable a is presented
in meters per second squared. A line passes through (0,...
