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.
*Problem 2: т An object is initially moving in the positive y-hat direction with a speed of 1 The object then explodes into three S m pieces.

As shown in the figure below, two blocks (m1 and m2) are each released from rest at a height of h = 3.53 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.15 kg,determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure.

This time it s a block of mass 1.91 kg sliding with a constant velocity of 4.88 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 3.41 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward.
