See explanation.

Explanation:

Momentum is calculated as a vector with value equal to product of velocity (#v#) and mass (#m#) and direction equal to the direction of velocity vector.

#vec(p)=m*vec(v)#

Here the value is:

#p=1/4*32=8 [kg*m/s]#

#8 \ "kg m/s"#

Explanation:

Momentum of an object is given by the equation:

#p=mv#

  • #m# is the mass of the object

  • #v# is the velocity of the object

So, plugging in our given values into the equation, we get:

#p=1/4 \ "kg"*32 \ "m/s"#

#=8 \ "kg m/s"#
