If you have an object hitting a stationary object of equal mass in an inelastic collision, what will happen?

a. the objects will collide and move forward in the direction that the first object was moving in.
b. the objects will collide and all momentum will transfer from the first object to the second object.
c. the objects will collide and stay stationary.
d. the objects will collide and bounce back.

a. The objects will collide and move forward in the direction that the first object was moving in.

Explanation:

Linear Momentum

The total linear momentum on an isolated system of particles is conserved regardless of their internal interactions. In a two-mass system, the total momentum is expressed as

where m1, m2, v1, v2 are the object's masses and speeds respectively.

If one object is at rest and the other hits it inelastically, then part of the kinetic energy is converted into other forms and both objects remain together at a speed we can compute, knowing that the total momentum after the impact is

Equating p=p'

Both masses remain at the same speed after the collision, so

Thus

Solving for v'

We know v2=0

Note both objects will move at a fraction of the original speed and in the same direction. Thus, the correct answer is

a. The objects will collide and move forward in the direction that the first object was moving in.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
