Answer:
p(i )=100 × 5=500 kgm/s
p(f)=100 × 8=800 kgm/s
force= change in momentum per unit time.
so plz. give some time for given change in momentum.

Initial velocity,
Final velocity,
Mass of the given object,
Time,
Initial momentum and final momentum =?
Magnitude of force exerted on the object =?
We know that,
Momentum, p = Mass × Velocity
Therefore, initial momentum,
= Mass × Initial velocity
Final momentum,
= Mass × Final velocity
We know that,
Now, force exerted on object
= Mass × Accleration
= 109 × 0.5
