HI BUDDY HERE IS YOUR ANSWER WITH FULL EXPLANATION .
I HOPE YOU WILL LIKE MY ANSWER.
SO, PLEASE MARK ME AS BRAINLIEST IF YOU LIKED MY ANSWER:-)
Answer:
(1.)Initial momentum(p₁)=500 kg.m/s
(2.)Final momentum(p₂)=800 kg.m/s
(3.)Force exerted on the object(F)=50 N
Step by step Explanation:
Given⇒ Mass(m): 100 kg
Initial velocity(u):5 m/s
Final velocity(v):8 m/s
Time(t)=6s
To find⇒(1.)Initial momentum (2.)Final momentum (3.)Force exerted on object.
Solution⇒(1.)Initial momentum(p₁)=Mass(m)×Initial momentum(u)
p₁=m×u
p₁=100 kg×5 m/s=500 kg.m/s
(2.)Final momentum(p₂)=Mass(m)×Final velocity(v)
p₂=m×v
p₂=100 kg ×8 m/s=800 kg.m/s
(3.)Force exerted on the object(F)=(Final momentum(p₂)-Initial momentum(p₁))/Time(t)
F=(p₂-p₁)/t
F=(800-500)/6=300/6=50 N
