PhysicsEasysingle choice

A simple pendulum $4 m$ long swings with an amplitude of $0.2 m$ . What is its acceleration at the ends of its path ? $(g = 10 m s^{- 2})$

Options:

Answer:

Solution:

$T = m g \cos θ$

$∴ F_{n e t} = m g sin θ$

and acceleration $= g \sin θ = g \tan θ$ as angle is very small $(\sin θ = \tan θ)$

$∴ a_{net} = 10 \times \frac{0.2}{4} = 0.5 m s^{- 2}$
