mass is 100 kg initial velocity is 5 ms-¹ find velocity is 20 ms-¹ find change in momentum
Answers
Answer:
1500kgm/s is the correct answer
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
⇒ mu = 500 kg m/s
Final momentum = mv = 100 × 8
⇒ mv = 800 kg m/s
Let us calculate the Force exerted on the object (F)
F = (mv – mu) / t
F = (800 – 500)/6
F = 300 / 6
F = 50 N
Initial momentum of the object is 500 kg m sˆ1.
Final momentum of the object is 800 kg m sˆ1.
Force exerted on the object is 50 N.
