You throw two objects, A and B, upward at the same time. The initial velocities are v0A = 0.8 m/s and v0B = [v0b] m/s. The blue curve in the figure shows the y-position as a function of time t for object A. At time t = t2, what will be the velocity of object B? Assume upward is positive. Provide your answer in m/s.
