A car of mass 1500kg moves to the right along a level straight road at a speed of 25 mph. It collides directly with a stopped motorcycle of mass 150kg. What is the total momentum after the collision?

p_initial = p_final
m_1*v_1i +m_2*v_2i = m_1*v_1f + m_2*v_2f
(1500)(11.17m/s) + 250(0m/s) = (1500 +250)v_f
v_f=9.57m/s
thus the total momentum after the collision would be:
m1+m2(9.57)
(1500+250) (9.57)
16747.5 kg m/s is the answer is this correct?
