An object of mass m moves to the right with a speed v. It collides head-on with an object of mass 3m moving with speed v/3 in the opposite direction. If the two objects stick together, what is the speed of the combined object, of mass 4m, after the collision? a. 2v
b. v/2
c. 0

Therefore, the correct option is c: 0.

Explanation:

We can find the speed of the combined object by conservation of linear momentum:

Where:

"i" is for initial and "f" is for final

m₁: is the mass of the first object = m

m₂: is the mass of the second object = 3m

v₁: is the velocity of the first object

v₂: is the velocity of the second object

Therefore, the correct option is c: 0.

explanation:

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
