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.

Solve the problems about momentum, impulse, the center of mass and conservation of momentum. 2. Determine the impulse of a 0.50 kg magazine at rest if thrown at 3 m/s.

A 1425 kg truck driving at 13.0 m/s collides elastically with a stationary 1175 kg car. If the car is traveling 14.25 m/s just after the collision, what is the velocity of the truck immediately after the collision? Assume that this is a perfectly elastic collision. Round your answer to the hundredths place. Final velocity of the truck = m/s
