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