Givem momentum=180kgm/s
          mass=15kg
 we no that momentum=massxvelocity
                velovity=momentum/mass
                           =180/15=12m/s
    The velocity of d objecct iz 12m/s

WE CAN SOLVE THIS QUESTION WITH THE FORMULA OF MOMENTUM
P=mv
HERE WE HAVE THE MOMENTUM =180kg m/s
AND MASS= 15kg
THERE FORE A/Q
180=15v
180/15=v
12 km/hr=v
there fore the velocity of the object will be 12 km/hr
