An object is in the region where potential energy is changing as shown in the figure. Its total mechanical energy is 30 J. If object is initially at C. Then select the correct statement.
Options:
Answer:
C
Solution:
Total energy E = 30 J. At C, U = -30 J, so KE = 60 J, not 50 J (B is false). The crest at D is at 35 J, which is above E, so the particle cannot reach D (D false) and cannot cross into the next well to reach E (A false). It stays trapped in the well about C and oscillates between the turning points on the slopes between B and D, where U = 30 J. Answer: (C).
