Answer:
#See solution for details.
Explanation:
Newton's Second law of motion states that :- the rate of change of momentum is directly proportional to the force applied on an object or system..
The force applied on an object of mass m is directly proportional to the product of mass and acceleration:
-Let be the initial momentum and be the final momentum.
#also let be the initial velocity and the final.
Momentum,:
#where k is the constant of proportionality. Given the direct proportion, k=1.
#The unit is in kgm/s but usually equated to N, 1kgm/s=1N
