Calculate the momentum of the following objects: a. 75kg speed skater moving forward at 16m/s

b. 135kg ostrich running north at 16.2m/s

c. 0.8 kg kitten running to the left at 6.5 m/s

momentum(M in Kgm/s)=mass(m in Kg) *velocity(v in m/s)

a) M=m*v. m=75kg,v=16 m/s

M =75*16

M=1200Kgm/s

b)M=135*16.2

M=2187Kgm/s

c)M = 0.8*6.5

M=5.2Kgm/s

Hope it is helpful?

atomic = no of protons.

mass number-atomic number = neutron number
