B) Para obter a velocidade do movel no instante 1-5s, escrevemos a função horária de velocidad v-10tv - 10 5-v-50 m/s Poderiamos também usar a fórmula de Torricelli vv+2gas 0+2 10 125-2500-5050 m/s Logo, a velocidade ao atingir o solo é de 50 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.
