the figure below, Anita is sprinting to the right with a velocity of VA, G = 5 m/s X^ relative to the ground. Balls 1 and 2 are thrown toward her by friends standing on the ground. Relative to Anita, both balls are approaching her with velocities VB1, A = 10 m/s X^ and VB2, A = - 10 m/s X^, respectively. Of the two, which Ball is thrown at the faster speed relative to the ground, Ball A or Ball B. Provide as detailed an explanation as possible of your answer. Your explanation could involve both words and math, but likely a little bit of math.
