Question

calculate the change in momentum of a body weighing 5 kg when its weight velocity decreases from 20 metre per second to 10 metre per second in 2 second​

Answer 1

Momentum's representation is p.
p=mv

p1=5 x 20 = 100kgms-1
p2 = 5x10 = 50kgms-1

Change in momentum = p1 - p2 = 100kgms-1 - 50kgms-1 = 50kgms-1
