Two air track carts move along an air track towards each other. Cart A has a mass of 440 g and moves towards the right with a speed of 1.59 m/s and Cart B has a mass of 295 g and moves towards the left with a speed of 1.08 m/s. What is the magnitude of the total momentum of the system?

Question

mani_jha · Answer

First convert the masses into kilograms. 440 g = 0.44 kg
295 g =0.295 kg
Momentum of A = mass*velocity
0.44*1.59
Momentum of B=mass*velocity
=0.295*1.08
Just add these two to get the total momentum

is this correct?
((0.44)(1.59))+((0.295)(1.08)) ?
I get the answer 1.02 kg m/s
