PROBLEM 2 Identical balls E and H have equal masses of 2 kg and equal cord 50° lengths of 1.50 m. Ball E is released from rest in the position shown. As a result of collision, ball E H rises by the angle B. Determine the angle B if the coefficient of H restitution is 0.7.

Choose True if the information found on the statement is CORRECT and false if it is INCORRECT. True False The center of mass can be represented by a pair of coordinates. The units of Impulse (N s) and Momentum (kg m/s) the same. Center of mass and the centroid of an object are always in the same place. We can locate the center of mass of a system even though it is constantly changing. It is possible to have perfectly elastic collision. Prolonging the time of contact between two objects increases the force of impact. You can change an object's momentum without changing its mass or velocity The coefficient of restitution be negative. When the coefficient of restitution is equals 0, it means that the objects stick together after collision. Elastic collision means that there is a noticeable loss of kinetic energy before and after the collision.

Please solve with detailed explanation. Thank you
