Problem
A particle of 1 kg of masses released from the top of a building with speed of 2 m/s at the end as shown in the figure. The mechanics energy of particle at 6 m before reaching the ground is....(g = 10 m/s2)
A. 2 joule
B. 120 joule
C. 122 joule
D. 240 joule
E. 244 joule
(Use mechanics energy conservation concepts to solve the problem. ME at 12 m equals ME at 6 m.)
