As shown in the figure below, object m = 1.55 kg starts at an initial height h = 0.340 m and speed v = 4.00 m/s, swings downward and strikes (in an elastic collision) object m = 4.65 kg which is initially at rest. 4.00 m/s h (a) Determine the speed of m (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.) m1 m m/s m/s (c) Determine the height (in m) to which each ball swings after the collision (ignoring air resistance). m m2 3 3
