# Given -
m = 500 g = 0.5 kg
u = 200 cm/s = 2 m/s
v = 0.2 m/s
# Solution -
Initial momentum of the object is -
pi = m.u
pi = 0.5 × 2
pi = 1 kgm/s
Final momentum of the object is -
pf = m.v
pf = 0.5 × 0.2
pf = 0.1 kgm/s
Change in momentum is calculated by -
∆p = pf - pi
∆p = 0.1 - 1
∆p = -0.9 kgm/s
Hence, change in momentum of object is -0.9 kgm/s.
