As shown in the figure below, object $m_1$ = 1.75 kg starts at an initial height $h_1$ = 0.325 m and speed $v_{1_i}$ = 4.00 m/s, swings downward and strikes (in an elastic collision) object $m_2$ = 4.60 kg which is initially at rest. (a) Determine the speed of $m_1$ (in m/s) just before the collision. m/s (b) Determine the velocity (magnitude in m/s and direction) of each ball just after the collision (Assume the positive direction is toward the right. Indicate the direction with the sign of your answer.) $m_1$ \\ m/s $m_2$ \\ m/s (c) Determine the height (in m) to which each ball swings after the collision (ignoring air resistance). $m_1$ \\ m $m_2$ \\ m
