True or false question:
Kinetic energy is a state scalar quantity and depends on reference system.
Which one of the following statements about the completely INELASTIC collision between two particles is NOT correct?
(A) They have common speed after collision.
(B) The kinetic energy of the system is conserved before and after the collision.

Homework Answers
in an inelastic collision the objects stick together and move with common velocity
the kinetic energy is not conserved in an inelastic collision
so option B) is the correct answer

True and False 1. If two particles of different masses have equal kinetic energy they also have equal momentum. 2. If the momentum of a single particle is zero, its kinetic energy may not be zero. 3. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. 4. A large force always produces a larger impulse on a body than a smaller force. 5. If the kinetic energy of a single particle is zero, its momentum must...

V If two particles of different masses have equal kinetic energy they also have equal momentum. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. If the momentum of a single particle is zero, its kinetic energy may not be zero. The linear momentum of an object is proportional to the mass of the object. A large force always produces a larger impulse on a body than a smaller force. If the kinetic energy of a...

One object is moving and one object is at rest. The two objects then collide in a dimensional, completely inelastic collision. So the two objects stick together after the collision and move off with a common velocity. Momentum of the two-object system is conserved. The masses of the two objects are 5.00 kg and 8.50 kg, respectively. The speed of the moving object masses 5.00 kg before the collision is 22.5 m/sec. Find the final speed of the two-object system...
