Microsoft PowerPoint Two balls A and B are initially at rest (VoA=0 and VoB= 0) at a distance d=50
m from each other. Ball A starts to move to the right with a constant
acceleration of a = 1 m/s2 and at the same moment ball B starts to move to the
left towards ball A with a constant acceleration of ag = 3 m/s2. After how many
seconds will the two balls collide?
