Answer:
yes
Explanation:
you will feel weary after shorter times
In practice, something that follows a very predictable pattern can be used as a time standard. This include things like radioactive decay, planetary orbit, and the speed of light, among others.
Answer:
a)
b)
c)
Explanation:
a) The angular velocity is related to the centripetal acceleration by the formula
, which for our purposes we will write as:

Since <em>we want this acceleration to be 1.5 times that due to gravity</em>, for our values we will have:

b) 1 rpm (revolution per minute) is equivalent to an angle of
radians in 60 seconds:

Which means <em>we can use the conversion factor</em>:

So we have (multiplying by the conversion factor, which is 1, not affecting anything but transforming our units):

c) The centripetal force will be given by Newton's 2nd Law F=ma, so on the centripetal direction for our values we have:

Answer:
(a) The least time required for the rotation is 50 seconds
(b) The corresponding value of α₁ is 1.6 rad/s²
