This is Newton's second law of motion.
It states that Force exerted on a moving object is directly proportional to its product of mass and acceleration.
i.e Force(F) = Mass(M) × Acceleration(A)
Because Force is constant here, reducing the weight of the body the force is applied to consequently reduces its mass.
If mass is reduced, the body's acceleration increases hence increasing its speed.
That is why the 40N dumbbell move faster.
Answer:
I'm pretty sure its 3m/s^2 for the acceleration but I don't know the force part sorry .
Explanation:
15m/s - 0m/s divided by 5 s = 3m/s
I'm no expert or anything so I could be wrong but this is the best I can give you. Sorry
Answer:
Newton
is the answer of si unit of force
For the answer to the question above,
220 m/s
<span>mass of the bullet * velocity of the bullet = mass of the gun * velocity of the gun </span>
<span>0.005 kg * v = 0.52 kg * 2.1 m/s </span>
<span>-> v = (0.52kg * 2.1 m/s) / 0.005 kg = 218.4 m/s
</span>I hope my answer helped you. Have a nice day!
