Concept Development Practice Page 5 2 - A ball tossed upward has initial velocity components 30 m/s. How much work (energy) is needed to lift an object that weighs 200 n to a height of 4 m? Skelly the skater, total mass 25 kg, is propelled by rocket power. What is the power output of an. 10 m/s 5 m/s 5 m/s 20 m/s 11.2 m/s 20.6 m/s 30.4 m/s conceptual physics 22 chapter 5 projectile motion. Neglect air drag and assume g = 10 m/s2.
