Agymnast practices two dismounts from the high bar on the uneven parallel bars. during one dismount, she swings up off the bar with an initial upward velocity of + 4.0 m/s. in the second, she releases from the same height but with an initial downward velocity of β3.0 m/s. what is her acceleration in each case? how do the final velocities of the gymnast as she reaches the ground differ?
