A body of mass 1 kg and velovity 10 m/s collides with another body if mass 3 kg and velocity 2 m/s comming from the exactly opposite direction. if on collision the body's much into one find the magnitude and direction of common velocity

Momentum = m1*V1  m2*V2= 1*103*2=4 in
the direction of m1.
m*V = 4
V = 4/m = 4/(1+3) = 1 m/s. in the direction of m1.
