An archer shot a 0. 06 kg arrow at a target. The arrow accelerated at 5,000 m/s2 to reach a speed of 50. 0 m/s as it left the bow. During this acceleration, what was the net force on the arrow to the nearest newton?.

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
