9. What is the difference between renewable energy and non-renewable energy and give one example of each: (keep it SHORT\") 10. Describe one advantage and one disadvantage of using YOUR Energy (from your assignment) to generate electricity? (keep it SHORT\") 2. A m Ck is thrown vertically upwards at 67 111/3. Find the height at which the m Ck is go i11g 23 111/3 [down]. SOLVE USING KINETIC Ex POTENTML ENERGY PLEASE Assume no air resistance. Thus at top, the total energy is Etop = 2294.5 m let at height h the speed of rock is 23m/ total energy at height is , F = 9. 8mh tim ( 23 ) 2 2 8, E = 9.8mh+ 264.5 m agerin, Etop = E =) 2249. 5 m = J.Smh+ 264.5 on " ) h= 2244.5-264.5 9.8 hence , h= 202 m This is the answerSolution:- at bottom the total energy y E bottom K. f + P. E = jm v 2 + 0 = 2294.5m J at maximum height the total energyy t top = Mah = 98mh J by conservation of energy Ebottom = Etop = ) 2 244. 5 m = 9.8 mh = ) hman 2247. 5 - 229 m 9.8
