, the y and z-components of the acceleration are zero and the x-component varies as given by the following function: ax(t) = -1 + 49t, where t is in seconds and ax is in meters per square second. The particle’s velocity at t = 0 was pointed towards the positive x-axis and has a magnitude of 26 m/s.

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.
