If its acceleration and deceleration are limited to 30fps and 20fps respectively, what maximum speed does it reach if the elapsed time is to be as small as possible? In addition, what is the displacement when it reach the maximum speed?Two identical billiard balls may move freely on a horizontal table. Ball A has a velocity of 0.4 m/s as shown, and hits ball B, which is at rest, at point C defined by = 40 (the line of impact is along 40° path with respect to the horizontal direction). Assuming no friction, and knowing the coefficient of restitution between the two balls is 0.75, determine the velocity of each ball after impact
