A large ball of mass M = 1.09 kg and initial velocity v (m-s-) collides plastically with a small stationary ball of mass m = 0.05 kg in the flat segment of the frictioness rolling track in Figure Q6. Determine the minimum initial velocity v (m-s-) of the large ball such that the collided balls overcome the two hills/bumps of the track (after the collision) if the highest point of the track is at heighth = 0.74 m from the horizontal plane. Provide only the numerical value in metres per second to one decimal place (e.g. 5.1) and do not include the units in the answer box. Partial credit is awarded for a reasonable approximation to the correct numerical answer. M EO Figure Q6: Plastic collision in frictionless rolling track h
