NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
A block attached to a spring executes simple harmonic motion with a displacement given by x(t) = A cos(ωt). If the amplitude A is 5 cm and the angular frequency ω is 2 rad/s, what is the maximum acceleration of the block?
A
10 cm/s²
B
20 cm/s²
C
5 cm/s²
D
40 cm/s²
Correct Answer
Option B
Detailed Explanation
The maximum acceleration in simple harmonic motion is given by a_max = Aω². Substituting A = 5 cm and ω = 2 rad/s, we get a_max = 5 cm * (2 rad/s)² = 20 cm/s².
