Answer:
The observer sees the space-probe 9.055m long.
Explanation:
Let be the length of the space-probe when measured at rest, and be its length as observed by an observer moving at velocity , then
Now, we know that and , and putting these into we get:
Thus, an observer moving at 0.95c observes the space-probe to be 9.055m long.
Answer:
1:4
Explanation:
The formula for calculating kinetic energy is:
If the mass is multiplied by 4, then, the kinetic energy must be increased by 4 as well. Since they will be travelling at the same speed when they are at the same point, the relation between KA and KB must be 1:4 or 1/4. Hope this helps!
