Write a short story, the story is to describe a motion activity appropriate for school that contains 2 acceleration segments. the two acceleration segments must represent different modes of acceleration

An astronomer at the equator measures the doppler shift of sunlight at sunset. from this, she calculates that earth’s tangential velocity at the equator is 465 m/s. the centripetal acceleration at the equator is 3.41  10 2 m/s 2 . use this data to calculate earth’s radius.
