For the same setup as in the previous question, what is the rotational kinetic energy of the spinning cube after the string unwi
nds L=0.30m? Use Energy methods. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Be careful with this problem. Both the spinning cube picks up kinetic energy as it spins up and the hanging mass gains kinetic energy as the string unwinds. Rotational kinematics will be necessary e.g.

Answer:
8.829 m/s²
Explanation:
M = Mass of Earth
m = Mass of Exoplanet
= Acceleration due to gravity on Earth = 9.81 m/s²
g = Acceleration due to gravity on Exoplanet
Dividing the equations we get
Acceleration due to gravity on the surface of the Exoplanet is 8.829 m/s²
