The equation of motion of Bob tells that the Bob starts with speed 8m/s and moves with constant acceleration 1m/s.
Therefore the 3rd graph (Acceleration vs Time) will be a straight line parallel to time axis. It's intercept on acceleration axis will be 1m/s2
2nd Graph (Velocity vs Time) Will be a straight line with upward slope of 1 and intercept on velocity axis will be 8m/s
1st graph (Although not clear but I am assuming x vs time) will be an upward parabola with apex at the origin.
