A) how fast must a meter stick be moving if its length is observed to shrink to 0.6 m? b) with what speed will a clock have to be moving in order to run at a rate that is one-half the rate of a clock at rest?

A)

0.8 c

B)

0.87 c

Explanation:

A)

L₀ = Original length of the meter stick = 1 m

L = Length observed = 0.6 m

= speed of the meter stick

Using the equation

= 0.8 c

B)

T₀ = Time of the clock at rest = t

T = Time of the clock at motion = (0.5) t

= speed of the clock

Using the equation

v = 0.87 c
