Two billiard balls of equal mass collide. Ball 1 is initially moving at 0.43 m/s to the left, and ball 2 is initially at rest. Which of the following sets of final velocities does not describe an
Inelastic collision between the balls?

Answer:

Explanation:

According to law of conservation of momentum;

m1u1 + m2u2 = (m1+m2)v

m1 ad m2 are the masses of the objects

u1 and u2 are their respective velocities

v is the common velocities

If their masses are the same, then m1 = m2 = m

u1 = 0.43m/s

m2 = 0m/s (body at rest)

Substitute and get v;

m(0.43) + m(0) = (m+m)v

0.43m = 2mv

0.43 = 2v

v = 0.43/2

v = 0.215m/s

Hence the final velocity of the inelastic collision is 0.215m/s
