Answer:
0.958 m
Explanation:
So the total mass of the system is
M = 1.93 + 2.95 + 2.41 + 3.99 = 11.28 kg
let y be the distance from the center of mass to the origin. With the reference to the origin then we have the following equation



So the center of mass is 0.958 m from the origin
6,000 in scientific notation is 6 x 10^3.

Answer:
0.80 c
Explanation:
The computation of speed is shown below:-
Here, The speed of the captain ship A report for speed of the ship B which is

where
indicates the speed of the ship A
indicates the speed of the ship B
and
C indicates the velocity of life
now we will Substitute 0.40c for A and 0.60 for B in the equation which is

after solving the above equation we will get
0.80 c
So, The correct answer is 0.80c
