AIPMT PRELIMS 2000 Physics Equations of Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
Motion of a particle is given by equation s = (3t³ + 7t² + 14t + 8)m. The value of acceleration of the particle at t = 1 sec. is :
A
10 m/s²
B
32 m/s²
C
23 m/s²
D
16 m/s²
Correct Answer
Option B
Detailed Explanation
Acceleration is the second derivative of displacement with respect to time. Differentiating s twice gives acceleration as 32 m/s² at t = 1 sec.
