Question

The amplitude of an oscillating simple
pendulum is 10 cm and its period is 4
s. Its speed after is after it passes its
equilibrium position, is
(1) Zero
(2) 0.57 m/s
(3) 0.212 m/s (4) 0.32 m/s​

Answer 1

Answer:

At Equilibrium

speed is MAXIMUM

Speed = Aw

w = 2π/T

T = 4

w = π/2

A - 10^-1

Vmax = 0.157m/s
