The speed of spaceship moving is 2.4 x 10^8 m/s
As from the given data, the clock in a spaceship is observed to run at a speed of 3/5 of a similar clock that rest on the earth is
T/T° = 3/5
The expression for the time dilation is given by
T = γT°
γ = T/T°
γ = 1/√1 - v^2/c^2 is time dilation
Substituting the values in the above equation as,
γ = T/T°
5/3 = 1/√1 - v^2/c^2
v^2/c^2 = 16/25
v = 0.8 c
v = 0.8 x 3 x 10^8 m/s
v = 2.4 x 10^8 m/s
Hence, speed of spaceship moving is 2.4 x 10^8 m/s

Answer:
B
Explanation:
Laboratories are usually controlled: however, in public places, there are way too many factors that could change an experiment
Let be the distance between the base of the ladder and the bottom of the wall, and the distance between the top of the ladder and the bottom of the wall, so that
Differentiate both sides with respect to time :
When , the top of the ladder is
above the ground. Then, given that the bottom of the ladder slides away from the wall at a rate of , we have
That is, the top of the ladder is sliding downward at a rate of 0.24 ft/s.
