Card 1 of 23
If right is positive, how is a velocity of 3 m s-1 to the left recorded?
A
For two particles in one dimension, conservation of momentum gives mAuA+mBuB=mAvA+mBvB\boxed{m_Au_A+m_Bu_B=m_Av_A+m_Bv_B}mAuA+mBuB=mAvA+mBvB.
B
The particles receive equal and opposite impulses.
C
-3 m s-1
D
The impulse of a constant force is I=Ft\boxed{I=Ft}I=Ft.
