A car is initially sliding backwards down a hill at -19 km/h. The driver accelerates the car. By the time the car's velocity is +25 km/h, it is +13.3 m from its starting point. Assuming the car was uniformly accelerated, find the acceleration.

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.
