a piece of clay with mass m is traveling with an unknown velocity in the positive x-direction, when it collides and sticks to a block of mass 3m, moving with velocity v=-3m/s. after the collision, the block and clay are stuck together and traveling with a velocity of 1 m/s in the negative x-direction. what was the original velocity of the clay mass?

Explanation:

= Mass of clay = m

= Mass of block = 3m

= Velocity of clay

= Velocity of block = -3 m/s

= Velocity of combined mass = -1 m/s

As mometum in the system is conserved we get

The original velocity of the clay mass was .

actually, no it isn't. when i was in junior high school, it was a blast. considering that it was a pre international baccalaureate school.
