Concept Development Practice Page 32 1 - W = mg = (1 kg)(10 m/s 2) = 10 m/s = 10 n, or simply, w = mg = (1 kg)(10 n/kg) = 10 n. Two cars, one twice as heavy as the other, move down a hill at the same speed. Felicia the ballet dancer has a mass of 45.0 kg. How much work (energy) is needed to lift an object that weighs 200 n to a height of 4 m? A moving car has momentum. What is the power output of an. If it moves twice as fast, its momentum is as much. Label the proton in the nucleus with a + sign and the orbital electron with a sign.
