Answer : The velocity of the spaceship is,
Solution :
As we are given that,
The speed of a spaceship = 7.58 wraps
So,
The speed of light =
Now put the value of speed of light in above expression, we get
So,
The velocity of the spaceship =
Now we have to convert the velocity of the spaceship m/s to cm/min.
Conversion :
(1 m = 100 cm)
(1 min = 60 sec)
The velocity of the spaceship =
Therefore, the velocity of the spaceship is,
