A 0.3 kg mass oscillates with amplitude 0.08 m. If its maximum kinetic energy is 0.096 J, what is the angular frequency?
Correct answer: C. 10 rad/s
- A. 5 rad/s
- B. 8 rad/s
- C. 10 rad/s
- D. 12 rad/s
Explanation
The maximum kinetic energy K = ½ mω²A². Substituting ; 0.096 = ½ (0.3)ω2 (0.08)2 . Solving gives ω = 10 rad/s.
