• Single object in motion

Given mass and momentum, solve for velocity

p=mv

v=p/m

 

  • Inelastic  collision (sticks) one object stationary

Given initial velocity and masses, solve for final momentum

 pinitial = m1v1initial + m2v2initial

pinitial = m1v1initial + 0 = pfinal

pfinal = m1v1initial

 

Given initial velocity and masses, solve for final velocity

m1v1initial + m2v2initial = (m1+m2)v(1+2)final

v(1+2)final = (m1v1initial) / (m1+m2)
