Two balls moving toward one another collide head-on. Ball 1, with mass 0.250 kg, is initially moving to the right with a speed of 2.00 m/s. Ball 2, with mass 0.550 kg, is initially moving to the left with a speed of 1.50 m/s. Immediately after the collision, ball 1 is observed to be moving to the left with a speed of 0.950 m/s. (a) Draw the ‘before’ and ‘after’ scenarios, clearly labelling the known velocities. (1)
