1. 4. A stone is dropped from the edge of a cliff and falls into the sea 72 meters below. The stone has a mass of 2 kg: air resistance on the stone may be assumed to have a constant value of 2 Newton’s. (gravity strength on Earth = 10 N/kg; a mass of 1 kg needs a 10 Newton force to lift it) D) What acceleration will this resultant force produce on the stone? Hi i have been assigned this but cannot find my notes on it and I am stuck could anyone please help?
