You are an astronaut (m = 115 kg) and travel to a planet that is the same mass and size as Earth. This new planet, however, rotates more rapidly with a period of only 4 h. Considering the centripetal acceleration caused by this rotation, what is the apparent weight that you would measure if you stepped on a scale at the equator of this planet?
