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...

Question 1 10 pts 1) A mass of 4 kg is moving at some velocity and collides inelastically with a 7 kg moving in the-x direction at 10 m/s. After the collision, both masses are moving in the -x direction and the total kinetic energy of both masses is 68 Joules. What was the momentum of the 4 kg mass before collision in kg m/s? Include a negative sign if moving in the negativex direction.
