Momentum after collision when both cars come to rest

00 kg m/s

Conservation principle in collisions

Momentum is conserved

Momentum before if momentum after is 00 kg m/s

00 kg m/s

Formula for momentum

p=mvp = mv

If 2 momentums add to 0, they are equal in...

Magnitude

Equation: momentum of car A = momentum of car B

mA×vA=mB×vBm_A \times v_A = m_B \times v_B

Car A velocity (mA=1000m_A=1000kg, mB=1500m_B=1500kg, vB=9v_B=9m/s)

13.513.5 m/s
