Answer:
Initial velocity of the object, u = 5 m/s
Final velocity of the object, v = 8 m/s
Mass of the object, m = 100 kg
Time take by the object to accelerate, t = 6 s
Initial momentum = mu = 100 — 5 = 500 kg m sˆ’1
Final momentum = mv = 100 — 8 = 800 kg m sˆ’1
Force exerted on the object, F = mv – mu / t
= m (v-u) / t
= 800 – 500
= 300 / 6
= 50 N
Initial momentum of the object is 500 kg m sˆ’1.
Final momentum of the object is 800 kg m sˆ’1.
Force exerted on the object is 50 N.

Answer: B
Explanation: The rocket is accelerating the the spacecraft. Accelerating relates to Newtons Second Law of Motion.
