Two objects collide and "lock together"
The velocities, directions and masses of each are known.
How do you solve the final velocity and direction of the new "object" made by both combined?

>> No.2600628

m1v1 + m2v2 = v(m1 + m2)

By learning high school physics.

Conservation of momentum. Work out total momentum prior to collision and its the same as your clumped objects after collision.

it is not that easy, it is a vector

Just providing the answer is better. OP will never actually learn to use or understand the ideas, will fall behind, inevitably fail his class. Thus, the world of science is safe from one more mind that is incapable of meaningful thought.

It really is that easy. Seriously, in grade 11 I could do this shit in my head.

FFS velocity IS a fucking vector

>>2600643
just fucking do the math

m1v1+m2v2/(m1+m2)=v

>> No.2600713

(((M1*V1)^2+(M2*V2)^2)^0.5)/(M1+M2)=Vfinal
