Answer:
We can also prove the conservation of mechanical energy of a freely falling body by the work-energy theorem, which states that change in kinetic energy of a body is equal to work done on it. i.e. W=ΔK. And ΔE=ΔK+ΔU. Hence the mechanical energy of the body is conserved
Explanation:
Answer:
16.93545 m
Explanation:
= Mass of astronaut = 93 kg
= Mass of satellite = 1400 kg
= Velocity of astrounaut
= Velocity of satellite = 0.15 m/s
As linear momentum of the system is conserved
As there is no acceleration
Distance = Speed × Time
The initial distance from the shuttle to the astronaut is 16.93545 m
Fusion is joining two things together while Fission is Dividing two things into pieces
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.
