A simple pendulum 4 m long strings with an amplitude of 0.2 m. What is its acceleration at the ends of its path? (g= 10 m/s2 )

Explanation

The acceleration of a simple pendulum at the ends of its path can be calculated using the formula: a = g * sin(θ), where g is the acceleration due to gravity and θ is the angle of displacement. At maximum amplitude, the angle is such that sin(θ) can be approximated for small angles. Given the parameters, the maximum acceleration is calculated to be 0.5 m/s2 at the extremes of its path.Option A is incorrect because the acceleration is not zero; it reaches maximum at the endpoints. Option B represents the gravitational acceleration, which is not the same as the pendulum's acceleration at maximum displacement. Option D is also incorrect because it overestimates the acceleration based on the given length and amplitude.
