mass of box = mass of block = M A block of width w is placed inside on the right of a box of length L. Both the block and box have the same mass, M, and are initially at rest. The surface between the block and box is frictionless. An external force Fis applied to the box that accelerates while the block slides until it strikes the left end of the box. During that time period what distance will the center of mass of the block-box system have moved? O b. L OC L-w od L 2 2

John's mass is 81.4 kg, and Barbara's is 56.1 kg. He is standing on the x axis at xj = +10.8 m, while she is standing on the x axis at XB = +4.64 m. They switch positions. How far and in which direction does their center of mass move as a result of the switch? Distance moved by center of mass = i eTextbook and Media

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.

A 10 g bullet moving at 1,000 m/s goes through a 1.0 kg block.  If the bullet goes through the block and comes out at a velocity of 711 m/s, determine the maximum height the block rises to.  Use g = 10 N/kg.
