Distance D = 5 cm = 0.05m
Revolutions = 33.33 per min => t = 60 sec
Acceleration is v^2 / r, so first we need to find velocity
Velocity = (D x 3.14 x r) / t => (0.05 x 3.14 x 33.33) / 60
Velocity = 0.0872 m/s
Acceleration = v^2 / r = 0.0872^2 / 0.05 = 0.152.

Because it has the lowest number. :)
Answer: Snakes are reptiles
Explanation: All reptiles are ectothermic (they obtain body heat from their environment).
Is there any numbers to your question?
Keep in mind, the energy is conserved in a pendulum.
