b) 45 kg m/s = ( 9 kg ) ( 5 m/s ) shows momentum being calculated
Momentum is mathematically defines as the product of the mass of a particle and its velocity. It is an impact what an object can produce if it collide .
Here
P = momentum , unit of momentum is kg m/s
m = mass , unit of mass is kg = 9 kg
and v = velocity , unit pf velocity = m/s = 5 m/s
momentum will be = 9 * 5 = 45 kg m/s
correct option will be
b) 45 kg m/s = ( 9 kg ) ( 5 m/s )
