Hockey Puck Momentum Conservation of Momentum
Hockey Puck Velocity
Clown Cannon
Consider the same system as before: A hockey puck with a mass of 0.17 kg is traveling to the right along the
ice at 15 m/s. It strikes a second hockey puck with a mass 0.11 kg. The first hockey puck comes to rest after the
collision. If conservation of momentum holds, what is the total final momentum of the system? (Round your
answer to the nearest tenth.)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
