A 2.55-m-long rod, as measured in its rest frame, speeds by you longitudinally at 6.11Ã10^7. You measure its length as it passes
1 answer:
Answer:
The length contracts by 54 mm.
Explanation:
According to theory of special relativity the contraction in the length of an object travelling at a speed 'v' is given by
where
L = contracted length of the object
= original length of object
v = speed of the object
c = speed of light
Applying values we get
Thus the change in length equals

Answer:
100N
Explanation:
Newton's third law states that whenever an object exerts a force on a second object, it exerts a force of equal magnitude and direction but in the opposite direction on the first. It is often stated as follows: Each action always opposes an equal but opposite reaction.
The subject 1 of 100kg is making a force F, to move an object from 50Kg to 2m / s ^ 2. This Force the object of 50Kg will reflect it in the opposite direction by Newton's third law.
Once the parameter of the force that both are experiencing is clarified, Newton's second law is applied to their respective calculation.
That is the force the boy exert on the man during the shove.
It’s solved by using a pretty standard formula for efficiency.
