Marijuana. Just took that test ;D

A second collision occurs when two objects collide again after the initial collision. This can happen if the objects bounce off each other or if they are in a situation where they are likely to collide again due to their motion or interaction.
In a collision, the second collision is when an unsecured driver strikes the inside of the vehicle.
No. "Experts have found it is usually the second collision that injures and kills people. When one car hits another car or object, this is the first collision. The second collision occurs when unbelted occupants are thrown into or around the car's interior or thrown from the vehicle. If an occupant is seat belted, there is no second collision" From http://www.fas.org/irp/agency/aia/cyberspokesman/99-07/safety2.htm
We have to assume that both bodies are initially moving along the same straight line in opposite directions, so the collision is "head on". We also have to assume that the collision is "elastic", meaning that none of the original kinetic energy is lost to heat. The final momentum is 20 Kg-m/s in the direction opposite to the original 80 kg-m/s motion.
he tortured his victims by cutting of limbs such as arms, hands, feet, ect. he did this for as long as he could.

From Newton's third law, when two bodies A and B collide, the force that A exerts on B is equal in magnitude but opposite in direction to the force that B exerts on A. From Newton's second law, this force produces a rate of change of momentum. Both bodies are experienced to the same magnitude in change of momentum but in opposite directions. Net change in momentum is zero. This implies that momentum is conserved.
In a crash, the second collision refers to the impact that occurs when a passenger or object inside the vehicle strikes another object within the vehicle, such as the dashboard or steering wheel, after the initial collision with another vehicle or object. This secondary impact can cause additional injuries to the occupants of the vehicle.

inelastic collision The formulas for the velocities after a one-dimensional collision are: where V1f is the final velocity of the first object after impact V2f is the final velocity of the second object after impact V1 is the initial velocity of the first object before impact V2 is the initial velocity of the second object before impact M1 is the mass of the first object M2 is the mass of the second object CR is the coefficient of restitution; if it is 1 we have an elastic collision; if it is 0 we have a perfectly inelastic collision
